6712SR Refrigerated Sampler
Section 1 Introduction
The 6712SR Refrigerated Sampler is an integral part of Teledyne
Isco’s comprehensive sampling system. The system includes the
6712SR and 6712SR Refrigerated Samplers, the 6712 Compact
Sampler, and the 6712 Standard Sampler.
The 6712SR is ideally suited for permanent installation in a wide
variety of indoor and outdoor environments. Constructed from
durable, corrosion resistant materials, the 6712SR withstands
the hostile environments of industrial and municipal monitoring
sites. However, do not install in locations where the refrigerator’s
lower compartment could become submerged.
The 6712SR accepts a variety of sequential and composite bottle
kits. Like all samplers in the 6712 series, it is compatible with a
variety of Teledyne Isco instruments.
6712 Front Panel

Section 1 Introduction
The appendices are:
• Appendix A, Menu Flowcharts
• Appendix B, Material Safety Data Sheets
• Appendix C, General Safety Procedures
• Appendix D, Replacement Parts
• Appendix E, Accessories List
1.2 About 700 Series
Modules
The bay on the controller’s side accepts any of Teledyne Isco’s 700
Series Modules. The 700 Series includes:
• 701 pH Parameter Module for monitoring pH and
temperature.
• 710 Ultrasonic Module for monitoring a flow stream’s
level and flow rate with an ultrasonic level sensor.
• 720 Submerged Probe Module for monitoring a flow
stream’s level and flow rate with a submerged probe.
• 730 Bubbler Flow Module for monitoring a flow stream’s
level and flow rate with a bubbler system.
• 750 Area Velocity Module for monitoring a flow stream’s
level, velocity, and flow rate.
• 780 4-20mA Input Module for interfacing to
non-Teledyne Isco devices with 4 to 20 milliampere
output signals.
The modules are optional accessories, and are not required for
operation. However, the modules offer a number of advantages:
they are an economical way to combine flow-rate or parameter
monitoring with sampling, and you can program the samplers
and modules as a single unit. Finally, the samplers store the
readings in memory.
1.3 SDI-12 Sondes
As an option, the sampler accepts up to 16 parameters from up to
ten sensors with SDI-12 addresses from 0 - 9 (refer to SDI-12
Sonde Readings, page 1-10, for specific parameters).
The data parameters used by the sensing device (sonde) and
recording device (sampler) must match. Certain vendors’ sondes
have enhanced commands that facilitate “plug and play” setup.
These Teledyne Isco Ready sondes can tell the 6712SR what
values they have, their order, and units of measure. Other sondes
can be used, but require manual setup to identify proper data
types for each data value reported.
1.4 Memory to Store
Monitoring Data
The samplers contain enough memory to store five sampling pro-
grams, sampling data, Teledyne Isco 700 Series Module readings,
and SDI-12 parameter readings. You can view the readings on
your sampler’s display.
You can also retrieve the readings and reports so the information
can be processed on a personal computer. Readings and reports
may be collected with a computer running Teledyne Isco’s
Flowlink™ software. Flowlink can download the information
through a direct connection, a modem connection (when the

Section 1 Introduction
sampler is equipped with the optional dial-out modem), or from a
581 Rapid Transfer Device (RTD). The RTD is a quick and simple
way to transfer the data from the field to your computer. Reports
are easily collected with Teledyne Isco’s Samplink software.
1.5 Pump Requirements
The pump requires a pump tube made specifically for the 6712
and 6700 Series samplers. These pump tubes are easily recog-
nized by their blue alignment collars. The 6712 pump tubing is
the same as that for Teledyne Isco’s 6700 Series samplers, but
different from Teledyne Isco’s earlier model samplers, such as the
3700 Series. Other types of pump tubing will not work in

2.1.3 Installing the
Distributor Arm and
Discharge Tube
The distributor arm is adjustable so that you can position the
discharge tube over the bottles of each kit. Each bottle kit also
correct discharge tube lengths for each bottle kit. If you are using
bulk tubing to cut your own tubes, cut the ends of the tube
square, not at an angle, and cut the length accurately.
The two-piece distributor arm has four positions, marked on the
underside with the letters A, B, C, and D. Adjust the arm to the
correct position for each kit. Thread the discharge tube through
Distributor Arm
1
the spring and arm so that the tube protrudes from the arm /16
1
to /8 inch. If too much tube protrudes from the arm it can catch
on bottles and jam the distributor arm.
Attach the arm to the distributor shaft extension. Secure the arm
to the extension with the black plastic nut. Slide the free end of
the discharge tube onto the bulkhead fitting. After installing the
distributor arm and discharge tube, run the distributor to each
bottle position to ensure proper installation.

6712SR Refrigerated Sampler
Section 2 Installation/Preparation
2.2 Installing Bottle Kits
Teledyne Isco ships the refrigerator from the factory with the
sample bottles in place. When using the sampler for the first
time, you will only need to remove the bottle lids. When
installing cleaned bottles or a new kit, keep these guidelines in
mind:
• Do not mix glass and plastic bottles together.
• Install all bottles to insure that they remain in place.
• Align the racks correctly. If the racks are misaligned, the
sampler may miss the bottle mouth, or the sampler will
deposit samples in the “wrong” bottle.
Each time you change from one size bottle to another, you must
adjust the length of the distributor arm, install a discharge tube
of the correct length, and possibly install a different distributor
shaft extension.
Each time you install a bottle kit, check the program settings for
the number of bottles and bottle volumes. Also rotate the dis-
tributor arm to each bottle position to ensure the arm is correctly
positioned over each bottle. Use the controller to move the arm.
2.2.1 Installing Racks
Install the bottle rack with bottles by sliding it into the cooling
compartment until the rack drops over the two semicircular
The five posts and two ramps which position the rack under the
distributor arm are adjusted at the factory. When you change
bottle kits, you may need to readjust the stops and ramps and
show you how to install the bottle kits.
Check the kit’s alignment by rotating the distributor arm. Do
not rotate the distributor manually. Moving the arm man-
ually damages the distributor drive. If you see any mis-
alignment, adjust the posts and ramps until the discharge tube
at the end of the arm stops over each bottle.

lon polyethylene bottles.
Begin by loosening the ramps. Move them
toward the front of the compartment so
that they will fit under the ridge of the lo-
cating base. (You can also remove them
completely.)
Remove the two front stops, and align the
holes on the sides of the locating base
with the holes for the stops in the mount-
ing plate. Secure the base by replacing
the stops.

Figure 2-4 Installing the 2-bottle Kit
2.2.2 Removing Racks
Before removing the rack, place the lids on the bottles so the
samples do not spill. Remove the bottle rack by lifting the front
edge of the rack slightly to disengage it from the two ramps.
Then, pull it straight out of the refrigerator. Be careful not to
catch the distributor arm against the bottles.
2.2.3 Installing Composite
Bottles
Remove the distributor arm and discharge tube. Remove the dis-
tributor arm stop. If using the two bottle locating base, remove it.
Slide the composite bottle discharge tube on the bulkhead fitting.
Composite bottle kits have two lids, one with a hole drilled in the
center. Screw the lid with the hole in it on the bottle, and place
the bottle in the center of the mounting plate.
Thread the discharge tube through the hole in the lid. Always
use the lid to retain the discharge tube. It prevents the sampler
from spraying liquid inside the sample compartment instead of
the bottle.

6712SR Refrigerated Sampler
Section 2 Installation/Preparation
2.3 Suction Line
The suction line is the tubing from the sampling point to the
pump intake. The 6712SR uses a /8-inch ID suction line of
3
lengths 3 to 99 feet. Teledyne Isco offers vinyl or Teflon® suction
lines. The Teflon® tubing has a polyethylene jacket to protect it
from kinks and abrasions.
The vinyl line contains a very low parts-per-million level of
phenols. If phenol content affects your sample analysis, use the
Teflon suction line.
When installing the sampler, be sure the vertical distance
between the liquid level and the pump is as small as possible.
2.3.1 Guidelines for
• Cut the line to the desired length but use the shortest
length feasible for the installation.
Measuring and Cutting
the Suction Line
• Cut the line in 1 foot increments. For instance, 4 feet,
1
not 3 /2. If using metric units of measure, cut the line in
increments of 0.1 meter. Do not include the length of the
strainer in the measurement.
2.3.2 Attaching Suction Line
to Pump Tube
Attach the vinyl suction line to the pump tube with the tube cou-
pling. Use the black clamp for the pump tube and the white
clamp for the suction line. Attach the line and tube to the cou-
pling by pushing them onto each end of the coupling. Then
tighten the clamps by squeezing the finger pads together. Loosen
a clamp by twisting it until its teeth disengage.
Attach the Teflon® suction line to the pump tube by inserting the
line into the tube and secure with a suitable clamp.
Attaching Suction Line Tube Coupling
2.4 Strainers
Teledyne Isco offers three styles of strainer that help prevent
solids from clogging the suction line:
3
•
/8-inch standard weighted polypropylene strainer for
routine and priority pollutant sampling
3
•
/8-inch stainless steel low flow strainer
• Weighted, CPVC-coated strainer for acidic liquid sources
install the optional low flow strainer in Teflon suction line, heat
the end of the suction line to make it more pliable, then carefully
screw the strainer’s threaded connector into the suction line.
2.4.1 Alternative to Strainers When sampling from high velocity streams with heavy sus-
pended solids, some field investigations suggest that more repre-
sentative samples are obtained without the strainer. Consider
attaching a short piece of thin walled aluminum tubing to the
end of the suction line; anchor the tubing so that the inlet opens
upstream. The aluminum tubing’s thin wall will not disturb the
flow stream, and most sample analyses disregard aluminum
ions. Under most conditions, the pre-sample purge removes any
debris over the tubing entrance.

2.5 How Does the Sampler When the sampler takes a sample, it draws liquid through the
strainer and suction line to the pump tube. The liquid flows
Work?
through the pump tube and past the liquid detector, which senses
the liquid. From the detector, the liquid follows the pump tube
through the pump to the bulkhead fitting and then through the
discharge tube to the sample bottle.
A typical sampling cycle consists of:
1. The sampler moves the distributor arm over the bottle that
is to receive the sample.
2. The pump reverses for the pre-sample purge.
3. The pump direction changes, filling the suction line.
4. When the detector senses liquid, the sampler begins mea-
suring the sample.
5. After depositing the sample, the pump again reverses for
the post-sample purge.
Sampling cycles vary somewhat according to program settings
for distribution. The sampler can move the distributor arm
clockwise and counterclockwise, making a number of distribution
methods possible. (In this manual, the words “sample event”
refer to a full sampling cycle for any distribution.)

Other variations include extended-program settings for
suction-line rinses and sampling retries. A sampler running a
program with line rinses completes the pre-sample purge and
then rinses the line. The suction line is purged after each rinse.
When programmed for sampling retries, the sampler will
attempt to pump a sample again if it fails on previous attempts.
2.5.1 Measuring Sample
Volume
“Sample volume” refers to the amount of liquid delivered into a
bottle. The volume is determined by the programmed value. The
volume is dependent on the volume per revolution of the pump,
which is dependent on the suction head. The 6712SR delivers the
sample by counting the pump revolutions and automatically
compensating for the suction head.

2.6 Installing the Sampler The following segment briefly describes initial sampler instal-
lation.
CAUTION
Tests indicate that the pump produces sound levels in excess
of 85db at one meter. Prolonged exposure to this sound could
result in hearing loss and requires the use of protective ear
plugs.
CAUTION
When using the 6712SR sampler with a 750 or 710 module,
transmitters such as cell phones or walkie talkies must not be
operated within 3 meters of the sampler. If water level readings
are fluctuating due to TV/radio station transmitter towers in the
area, the sampler must be relocated.
WARNING
The 6712SR samplers have not been approved for use in
hazardous locations as defined by the National Electrical
Code.
WARNING
If you must enter a manhole or other dangerous location to
install the sampler, observe standard safety precautions.
Refer to Appendix C for a discussion of safety
considerations.
2.6.1 Tips for Routing
Suction Line
Route the line so that it runs continuously downhill from the
sampler to the liquid source. This helps drain the line during
pre-sample and post-sample purges. When the sampler is used in
below freezing temperatures, there is a risk of the suction line
being frozen. A suitably warm sampling source can usually
prevent this, provided there are no loops in the suction line.
Some situations may require more protective measures, such as
insulation of the suction line, or heat tape. Thoroughly draining
the suction line minimizes the possibility of frozen liquid
clogging the line.
2.6.2 Intake Placement
For representative samples, place the intake in the main current
of the flow stream, not in an eddy or at the edge of flow. Placing
an intake at the bottom may produce samples with excess heavy
solids and no floating materials, while placement at the top may
produce the opposite conditions.
2.6.3 Positioning a Sampler
Place the refrigerator on a relatively flat, horizontal surface.
Placing the refrigerator on a steep incline may cause the sample
to miss the bottle mouth.

between the level of the liquid and the pump is as small as pos-
sible.
CAUTION
The refrigerator’s lower compartment is not watertight. Do not
install in a location where the refrigerator’s lower compartment
could become submerged.
2.7 Connecting External
Instruments
The 6712SR sampler can be used in conjunction with several
types of external instruments.
2.7.1 Flow Meter
To connect the sampler to a teledyne Isco open-channel flow
meter, 4100 series flow logger, 2100 series flow module, or 1640
Liquid Level Actuator, attach the sampler-to-flowmeter cable to
the Flow Meter Connector. To connect the sampler to a
closed-pipe flow meter, attach a teledyne Isco 4-20 mA Input
Interface device to the sampler’s Flow Meter connector. Plug the
line cord into an AC power outlet. Be sure it is connected to 120
volts AC (optional 230 volts AC). When using the sampler with
an external instrument, remember these guidelines:
Flow Meter Connector Icon
• Both the sampler and the flow instrument must be on
and running a program.
• If using a flow meter, logger, or module for flow pacing,
the sampler and the flow instrument must both run
programs with flow pacing settings.
• If using a flow meter or flow logger for trigger pacing,
the sampler must run a program with flow pacing
settings, and the flow instrument must run a program
with trigger pacing settings.
• When the sampler runs an event-paced program, it
disregards pacing pulses from a flow meter or flow
logger. However, the sampler continues to monitor for
enable signals.
2.7.2 Rain Gauge Connector
Connect the rain gauge, SDI-12 Sonde, or Refrigerator Temper-
ature Sensor connect cables to the nine-pin Rain Gauge Con-
nector. When connecting a rain gauge and an SDI-12 Sonde, or
rain gauge and a Refrigerator Temperature Sensor, use the
appropriate Y-connect cable. See the Accessories appendix at the
end of this manual.

2.8 Locking the Sampler
2.9 Servicing the Sampler
The refrigerator is equipped with a lockable latch for the top
cover and a lockable catch for the door handle. To lock the refrig-
erator, use two padlocks, one for the top cover and one for the
door.
Servicing the sampler includes:
• Collecting the filled sample bottles and replacing them
with clean bottles;
• Collecting the data recorded by the sampler during the
program.
Samplers are usually serviced after they complete a sampling
program. When working up a service schedule, you will need to
estimate the program completion time. You should also be
familiar with the program’s settings for the start time or if the
sampler is programmed for continuous sampling.
Continuous sampling is controlled by the distribution setting
entered at the “RUN CONTINUOUSLY?” screen. A “YES”
response directs the sampler to reset the distribution sequence
and continue the countdown to the next sample event. Appro-
priate service intervals will prevent overfilled bottles.

6712SR Refrigerated Sampler
Section 3 Getting Started
Before programming the 6712SR, you should become familiar
with its keys and how to use the screens.
The 6712SR Sampler has two sets of programming modes. The
first mode, Standard Programming, lets you set up typical
sampling programs easily and efficiently. The second mode,
Extended Programming, lets you create sophisticated pro-
grams for complex sampling applications.
All of the sampling features available in standard programming
mode are available in extended programming mode. However,
extended programming provides many additional features.
Standard and extended programming features are explained in
separate sections. This section focuses on some basic features
that are common to both programming modes, such as using the
menus and setting the clock.
3.1 Initial Operation
Turn the sampler on by pressing the On/Off key. It is labeled with
this icon:
. The start-up screen appears first.

The sampler is programmed at the factory so that the standard
programming screens appear when you first turn the sampler on.
You can switch between programming modes by typing in a
numerical command at the main menu:
• At the main menu type 6712.2 to show the extended
programming screens.
• At the main menu type 6712.1 to show the standard

The sampler will continue to use the program mode you selected,
even if the sampler is turned off and on again, until you man-
ually switch to the other programming mode.
With the display backlight activated, the screen will glow for
several seconds following your last keystroke.
If you press a key and the screen text does not change, it is
probably because the keystroke turned the backlight on, instead
of performing its function. Press the same key again.

3.5 Menu Screens: Site
Descriptions and
Program Names
The sampler has two text-entry menus, one for site description
and another for an extended-program name. They work in the
same way. A site description is commonly a number, address, or
other short note that helps identify the monitoring site.
Extended programming has a similar screen that lets you enter
program names for stored programs.
The example to the lower left shows how to change the site
description from FACTORY01 to SITE 29. Line 1 contains text
between two quotation marks. Lines 2 and 3 contain the menu
options — numbers, letters, and punctuation marks — used to
spell out the description. In line 3, the space between the
ampersand (&) and the double quotes (") is a space character.
Line 4 contains two additional options:
• BACK-UP, an option that moves the cursor on the text
line to the left one character.
• DONE, an option that tells the sampler to save the text.

3.6 Messages
The sampler has four sets of messages that supplement the pro-
gramming screens. Information messages tell you about pro-
gramming status. Help Notes are brief comments associated
with programming screens describing the setting or offering
assistance. Warning messages tell you something is different
tha teledyne Isco’s standard. Operation messages report the
sampler’s status as it runs a program.

3.6.3 Warning Messages
Warning messages appear when the sampler determines some-
thing is out of the ordinary. For example, the following warning
appears when you type a number that is larger than the
standard bottle volume:
BOTTLE VOLUME IS
3500 ml (300-30000)
WARNING!
STANDARD BOTTLE
VOLUME EXCEEDED!
The 6712 does accept nonstandard volumes because you might
use a nonstandard container occasionally. For a list of recom-
mended volumes for Teledyne Isco bottles press the ? (Help) key
at the “Bottle Volume Is” screen, or refer to the Technical Specifi-
cations.
The 6712 uses the bottle and sample-volume settings to
determine the maximum number of samples that can be
deposited without overfilling the bottles. Entering a volume that
exceeds the standard volume may cause the sampler to overfill
the bottle.
3.6.4 Operation Messages
An operation message reports the sampler’s status as it runs a
program. An example is shown below.
PROGRAM WILL START
AT 06:00 TU 20-FEB
05:56:22 TU 20-FEB
3.7 Menu Trees
Selecting a menu option will take you to a number-entry screen
or another menu screen. The screens are organized in a
branching structure that resembles a tree. Refer to Figure 3-1 for
a simple chart of the menu tree for standard programming. The
standard programming structure is different — much simpler —
than the extended programming structure. Charts that show you
most of the sampler’s screens appear in Appendix A.
The entire structure changes a little when a module is attached
because the sampler adds a set of screens for a module as soon as
it detects the module’s presence. The manuals for each module
contain menu trees for its programming screens.

All of the sampling features available within the standard pro-
gramming screens are available in extended programming.
However, extended programming provides several additional fea-
tures which are discussed in the next section. Menu flowcharts
for both sets of programming screens are in Appendix A.
4.1 Switching Between
Standard and
Factory default settings cause the sampler to begin in standard
programming mode the first time you turn it on. The start-up
screen tells you which programming mode the sampler is cur-
rently using. You can switch between programming modes by
entering a numerical command at the main menu:

4.4 Pacing
Sample pacing is the rate at which the sampler takes samples.
Depending on the type of pacing you select, the rate is controlled
by the sampler’s internal clock or by inputs received from con-
nected instruments.
Standard Time Pacing and
Flow Pacing Screens for
Samplers without Flow
Modules
Standard programming provides time pacing and flow pacing
(refer to Step 7 in the previous two programming examples). In
time-paced sampling, the interval between samples is a constant
time interval. When you program the sampler for time pacing,
the sampler prompts you to enter the time between sample
events in hours and minutes. Time paced programs always take
a sample at the start time.
TIME PACED
FLOW PACED
• When programming, you will
be asked to select time or flow
paced sampling. Depending
upon your choice, you will see
one of the following screens:
Flow paced sampling requires a flow meter, flow logger, or a
module. A flow meter or flow logger paces a sampler by sending
an electronic signal to the sampler after measuring a specified
volume of liquid. Because each pulse represents a volume
interval, flow pacing rates are proportional to the volume of
water flowing through the channel.
TIME BETWEEN
SAMPLE EVENTS:
__ HOURS, __ MINUTES
FLOW BETWEEN
SAMPLE EVENTS:
____ PULSES (1-9999)
When you program the sampler for flow pacing and are using a
flow meter or flow logger, the sampler prompts you to enter the
interval between sample events in pulses. The sampler initiates
a sample event when the set number of pulses is received. Pro-
grams that are flow paced do not take a sample at the start time.
After setting the program start time, you will be prompted to
enter a maximum run time of zero to 999 hours. If you would like
the program to run indefinitely, enter 0 (zero) for maximum run
time.
Flow Pacing Screen for
The flow pacing screens change when you attach a flow module
(see example to the left). Because the sampler is more closely
integrated with the modules, the standard flow pacing screen
prompts you for the flow volume between sample events instead
of pulses between events. The flow volume units displayed are
what you had previously programmed.

4.4.1 Trigger Pacing
Teledyne Isco 4200 Series Flow Meters and 4100 Series Flow
Loggers send pulses for trigger pacing. The flow meter or flow
logger sends pulses at two different time intervals when trigger
pacing a sampler. Trigger pacing, for example, lets you sample
less frequently when the trigger condition — a condition based
on level, flow, or rainfall — remains below a set point. The
intervals are determined by the flow instrument’s program set-
tings for trigger pacing.
When conditions change and readings pass the set point, trig-
gering the new rate, you can sample more frequently. Or, when
the trigger condition is a clock setting, the instrument changes
the pacing interval according to the time of day. Using a clock
trigger condition, for instance, the flow meter or flow logger can
pace the sampler slowly at night and more frequently during the
day. (For more information about trigger pacing, see your flow
meter or FLOWLINK manual.)

6712SR Refrigerated Sampler
Section 4 Standard Programming
The flow meter or flow logger sends the same pulse for both flow
and trigger pacing, and the sampler cannot distinguish between
them. Therefore, to program a sampler for trigger pacing, simply
program it for flow pacing.
4.5 Distribution
Distribution describes how the sampler is to deposit samples. A
sample is the volume of liquid deposited in a bottle. A sample
event includes the full sampling cycle and may deposit a sample
into more than one bottle.
In standard programming, you can program the sampler for
these different distribution methods:
• Sequential
• Bottles Per Sample
• Samples Per Bottle
• Composite
4.5.1 Sequential
In sequential distribution, the sampler deposits one sample in
each bottle. A sequential sample represents a “snapshot” of the
flow stream at a point in time.
4.5.2 Bottles Per Sample
In bottles per sample distribution, the sampler deposits a sample
in each of a set of bottles. A bottle set includes at least two bottles
but may include all bottles. Use bottles per sample when the
volume to be collected is larger than the amount one bottle can
hold or when you need identical samples.
4.5.3 Samples Per Bottle
4.5.4 Composite
In samples per bottle distribution, the sampler deposits samples
from several sample events in a single bottle before moving to the
next bottle. Use samples per bottle distribution to collect a series
of small composite samples.
For single bottle configurations, samples per bottle distribution
is known as composite sampling. A composite sample represents
an average of the flow stream’s characteristics during the sam-
pling period.
4.5.5 Continuous Sampling
Sample programs can be run indefinitely by selecting “YES” at
the “RUN CONTINUOUSLY?” screen. Continuous sampling
resets the distribution when the distribution sequence is com-
plete. That is, when the last bottle/set is reached, the next
bottle/set is the first bottle/set. All pacing modes except
RANDOM are supported.
When running a program continuously, the bottles must be ser-
viced at regular intervals to prevent overfilling the bottles. The
sampler assumes that the next bottle/set is empty and ready to
receive samples.
The figure on the next page steps through the programming
screens for sequential, bottles per sample, and samples per bottle
distribution.

Section 4 Standard Programming
4.6 Start Times
It is important to understand the difference between the time at
which you run a program and the program’s start time. Running
a program simply means selecting RUN from the sampler’s main
menu. The start time is the time at which the sampler begins the
program’s first sample interval countdown. The start time is con-
trolled by your selections from the start time screens.
Each program contains start-time settings that tell the sampler
when to begin the program. When programming the sampler, you
can select one of four start time options: NO DELAY TO START,
DELAYED START, CLOCK TIME or WAIT FOR PHONE CALL.
• Select NO DELAY TO START when you want the
sampler to start as soon as you select RUN.
• Select DELAYED START when you want the sampler to
delay from 1 to 999 minutes before starting the
program.
• Select CLOCK TIME when you want the sampler to
begin the program at a specific time on at least one day
of the week.
• Select WAIT FOR PHONE CALL when you want the
sampler to begin the program after receiving a remote
command to start.
4.6.1 How Do Start Times
Work?
As soon as you select RUN from the main menu, the sampler
checks the program’s start time settings. With a “DELAYED
START” setting, the sampler starts a countdown to the start
time. The period between the time you select RUN and the start
time you’ve specified in the program is called the “delay to start
time.”
When you run a program with “CLOCK TIME” settings, the
sampler also starts a countdown to start time until the day of
week and clock times are met.
The sampler may not collect a sample at the start time. The
sampler must be enabled, and the pacing selected must call for a
sample at start. In any event, the sampler checks the pacing set-
tings and begins the pacing-interval countdown.

4.6.2 Sampler
Enable/Disable
Teledyne Isco flow meters and flow loggers have a programmable
sampler-enable feature that lets them enable (start) or disable
(stop) a program according to certain monitored conditions. For
example these conditions can be level, flow rate, pH, temper-
ature, percent, rainfall, I/O; or a combination of two conditions.
The 1640 Liquid Level Actuator can also be used, as well as any
other instrument that can ground the input to pin F. Grounding
the input disables the sampler.
The sampler disregards disable signals during the delay to start
time. However, when the sampler detects a disable signal at the
start time, it suspends the program until it is enabled. The

4.7 Running Programs
To run a program, select RUN from the main menu. You may also
select YES at the RUN THIS PROGRAM NOW? screen at the
end of the programming screens.
4.7.1 Run Time Screens
While running a sampling program the sampler displays a
variety of messages that report the program’s status. For
example, if the sampler has not yet reached the programmed
start time, it displays the scheduled start time as well as the
current time.
Once the program reaches the start time, you can determine the
time of the next sample, the next bottle to receive a sample,
sample distribution, and other information. Other messages
appear while the sampler runs through a sampling cycle and
takes a sample. When the sampler needs to report multiple mes-
sages, it alternates them, displaying each for one to three
seconds.

An * (asterisk) appears next to the reading if the module was
unable to take a reading. If an asterisk appears, the reading dis-
played is the last available reading. Flow rates will be reported
as zero flow if the error persists for more than five minutes (for a
level or velocity reading that flow is calculated from).
If an entire reading is filled with asterisks, the value exceeds the
number of characters that can be displayed. The sampler stores
the actual reading in memory, so it may be collected later.

Keep in mind that any totalizer values will be reset at the start
time. Module and sonde readings are also displayed after a
program is complete, until a key is pressed.
It is not necessary to run a program to view module or sonde
readings. Real time data can be viewed on the display by
selecting “VIEW REPORT” from the main menu.
4.8 Interrupting a
Running Program
You can interrupt a sampling program by pressing the Stop key
while the sampler is waiting for the next sample event. Pressing
Stop places the sampler into Manual Paused operation and
records a manual pause in the sample event log.
In this state, the sampler allows you to access several functions.
You can modify the program, reset alarms, take a grab sample,
etc., without adversely affecting the running program. Modifying
the program is limited to adjusting the pacing intervals, enable
conditions and sample volume. The basic program structure,
such as the type of pacing, can not be changed.
While in the manual paused state, the sampling program con-
tinues to operate as normal, with the exception of taking
samples. If a sample was to be taken, it is skipped. The sampler
records “sample skipped” in the sample event log and continues
to operate as normal.
The manual paused state displays a scrolling menu with several
options (see example below). Use the Arrow keys to scroll
through the manual paused options and the ↵ key to make a
selection. Return to the running program by selecting resume
program or pressing the Stop key. If you do not make a selection,
the sampler automatically resumes the original sampling
program five minutes after the last key was pressed.

4.8.4 Grab Sample
When selected, you will be asked to enter the volume to be

container outside the sampler base. Do this by removing the
pump tubing from the bulkhead fitting. See Grab Samples on
4.8.5 Pump Tube Alarm
4.8.6 Calibrate Volume
If the pump tube is changed, this option should be selected to
reset the pump counts on the counter. This will remove the
“WARNING: REPLACE PUMP TUBING” message that may
appear while the program is running. A pump tube replaced
message is logged. See Replacing The Pump Tube in Section 7,
Maintenance.
When selected, you will be asked to enter the volume to be
pumped. A sample will then be taken as if it is to be placed into a
container outside the sampler base. Do this by removing the
pump tubing from the bulkhead fitting.
After the sample has been pumped, you will then be asked to
enter the amount actually delivered. Once you have entered the
delivered volume and accepted the calibration, a volume
delivered event will be logged.
4.8.7 Cal/Adj Parameters
When the sampler is configured for operation with a module, this
option becomes available. Selecting this option will display the
appropriate level adjustment screens and/or the calibration
screens. If the level is adjusted, an adjusted level event is logged.
If a parameter is calibrated, an appropriate event is logged.
Calibrating a parameter probe will temporarily “turn off” the
partition data storage and the sample enable/disable functions.
These functions are disabled during the calibration and for five
minutes after the program is resumed. During this time,
parameter data normally collected at the data storage interval
will be logged as a 252 error message.
4.8.8 Adjust Pacing
This option is available when the running program is paced by
Time, Flow Pulses or Flow Volume. If you select this option, you
are asked to enter a new pacing interval. The sampler logs an
interval changed event.
The original pacing interval continues to count down until you
return the sampler to the running program (select resume
program). If the new pacing interval is less than the original
count remaining, the new interval is used.
4-13

If the original count remaining is less than the new pacing
interval, the original count will continue to count down to the
next sample event. Subsequent samples are then paced by the
new interval.
4.8.9 Adjust Volume
4.8.10 Power Used
Select this option to change the sample volume within the limits
of the currently programmed sample distribution. If you change
a sample volume, a volume changed event is logged.
The 6712 has a “fuel gauge” that gives an indication of power
usage. The controller keeps track of how much power has been
consumed since the last time it lost power. If the controller is
powered by an external battery, this fuel gauge can help you
estimate the condition of the battery.
Keep in mind that the sampler has no idea as to how much
charge was originally stored in the battery (or even if a battery is
being used), and therefore has no idea as to the remaining
capacity of its power source.

4.12 Calibrate Volume
The sampler delivers accurate sample volumes without cali-
bration. If you find that sample volumes vary significantly from
the programmed values, first check the suction line for proper
installation. Be sure it slopes continuously downhill to the liquid
source and drains completely after each sampling cycle. Then,
compare the actual length of the suction line to the suction line
length settings in the program to see that they match. Also check
the pump tube for excessive wear and replace it if necessary.
You may want to calibrate when:
• A new pump tube is installed. Run the pump for five
minutes before calibrating.
• The sample source is above the sampler.
• Sampling from pressurized lines (15 PSI Maximum).
4.12.1 Calibration Tips
• For the best results, calibrate the sampler after it’s
installed on site.
• Use a graduated cylinder for volume measurement.
• The sampler clears the previous calibration setting
when you reinitialize the sampler.
• You cannot calibrate while the sampler is running a
program.
• When the sampler delivers the sample, it runs through a
complete sampling cycle, using the current settings for
volume line rinses and retries. If it is a two part
program, the sampler uses the volume setting for part
A.
To calibrate:
1. Disconnect the pump tube from the bulkhead fitting.
2. Place the end of the tube over a collection container.
3. Follow the steps in Calibrating Sample Volumes in the
margin.
4. Reconnect the pump tube to the bulkhead fitting.

4.13 Operating the Pump
You can manually operate the sampler’s pump in the forward or
reverse direction. You can do this to test the pump, draw a large
sample, or purge the suction line.
When you run the pump manually, the sampler reports the
number of pump counts during the pump’s operation. Use this
feature to obtain an estimate of the pump counts required to
purge a nonstandard suction line.
You can also manually run the pump from the main menu. Press
the “1” key and then ↵ to run the pump in reverse. Press the “3”
key and then ↵ to run the pump forward.

4.15 Reports
The 6712 records a variety of data while running a sampling
program. It uses the data to produce four reports:
• The Program Settings report, listing the program
settings.
• The Sampling Results report, listing the program
settings, time of samples and other program events.
• The Combined Results report, combining the sample
event times with rainfall or module data.
Interrogator Icon
• The Summary report, listing daily summaries of data
collected. The Summary report may be rainfall and/or
module data.
The sampler stores the data for each report in memory where
they remain until you select RUN. Selecting RUN clears the
memory so that it can store the data from the next program.
4.15.1 Collecting Reports
There are a number of ways to collect the reports:
View reports (program settings, sampling results, and abbre-
viated summary reports) on the sampler’s display.
Collect the reports (except for summary reports) with a teledyne
Isco 581 RTD and use a computer running flowlink or samplink
to transfer the reports from the RTD to a file on the computer.
Collect the reports (except for summary reports) with an IBM PC
or compatible computer running flowlink.
Collect the reports with and IBM PC or compatible computer
running samplink.
581 RTD
4.15.2 Viewing the Data
Because the display area is small, the data on the reports will be
displayed a little differently from the data that is transferred to
and viewed on your computer.
• For the Sampling Report, the sampler displays each
program event, one at a time.
• For the Module and Rainfall Data reports, it displays
daily summaries, instead of the full reports available
with the rtd, Flowlink, or Samplink.
If you select Sampling Report or Rainfall (step 3 in Viewing Data,
shown in the margin), the sampler begins displaying the report
data. The sampler advances automatically through the report
items, displaying each item briefly. While the sampler advances
automatically through the displays:
• Stop the automatic displays by pressing Stop once.
Then, use the arrow keys to move manually through the
report.
• Return to the main menu by pressing Stop twice.
At the end of the report, the sampler leaves the last item dis-
played until you press:
• the arrow keys to move forward or backward manually
through the report.
• Stop to return to the main menu.

• ↵ to start the automatic displays again.
Viewing Data
If you select Module Data in step 3, the sampler displays the
screen shown in step 4. Select the Daily Summary option and the
sampler displays the stored data just as the Sampling Report
was described above. Selecting the Current Readings option
causes the sampler to display real-time readings. When there are
multiple screens, they will be displayed alternately. You can
quickly advance through the screens by pressing an arrow key or
↵. Pressing Stop exits the Current Readings mode.

4.15.4 Sampling Results
Report
As the sampler runs a program, it records the program’s events.
Program events include such items as sample events, program
event with a short description. You can view the report by fol-
as the Sampling Results report.
In the text file version of the report, sample-event entries include
the time of the event as well as the sample and bottle numbers.
The sample column contains the sample number deposited into
the bottle. This information reflects the distribution selected for
the program.
The letters in the Source columns are codes for the cause of the
event. The letters in the Error column are codes for the causes of
missed samples. The source and error codes appear with expla-
nations at the end of the report. A list of codes appears in Table
The last column in the Sampling Results report records the
pump counts for the sample event. Large variations in pump
counts from event to event indicate fluctuating heads, a relocated
suction line, or a temporarily clogged strainer.
4.15.5 Combined Results
Report
At the time of each sample event, the sampler records the
readings from each connected module, rain gauge, or SDI-12
sonde. The Combined Results Report presents the event time,
sample and bottle number, and the respective readings from the
device.
For flow modules, the readings are level and flow rate. For the
pH module, the readings are temperature and pH. For the rain
gauge and SDI-12 Sonde, the readings vary according to the
selections enabled during the hardware setup in extended pro-
gramming. When recording four or more sonde parameters, the
Combined Results report will exceed the standard 40 character
width. To read the additional columns, the data must be collected
with Flowlink 4 for Windows software.
4.15.6 Summary Report
This report summarizes the rain gauge or module data. The
types of readings are the same as those available to the Com-
bined reports. The sampler compiles the data to present a daily
total, the day’s average, maximum, and minimum reading, and a
listing of hourly averages. The sampler then graphs the day’s
readings.

4.17 Programming for 700
Series Modules
The bay on the controller’s side accepts any of Teledyne Isco’s 700
Series Modules. These modules are optional accessories that are
not required for operation of the 6712. However, the modules
offer an economical way to combine flow-rate or parameter moni-
toring with sampling.
The programming of these modules is integrated with the pro-
gramming of the sampler, so attachment of a module will cause
different screens to be displayed, depending on the type of
module and the selections you make while programming.
Two modules that are commonly used are the 730 Bubbler
Module, which monitors a flow stream’s level and flow rate, and
the 750 Area Velocity Module for monitoring a flow stream’s
level, velocity, and flow rate. The following sets of screens give

6712SR Refrigerated Sampler
Section 5 Extended Programming
The 6712SR Sampler has two sets of programming screens. The
first set, called standard programming screens, lets you set up
typical sampling programs easily and efficiently. The second set,
extended programming screens, lets you create sophisticated
programs for complex sampling applications.
All of the sampling features available with standard pro-
gramming screens, discussed in Section 4, are available with
extended programming screens. However, the extended screens
provide several additional features and some screen display dif-
ferences which are discussed in this section. The menu flow-
charts for both sets of programming screens are in Appendix A,
Menu Flowcharts.
Note
This section assumes that you have read, and are familiar
with, the instructions in Section 4, Standard Programming!
5.1 Extended and
Standard Mode
The sampler is shipped with factory default settings in standard
programming mode when you first turn the sampler on. The
start-up screen tells you which programming mode the sampler
is currently using. You can switch between programming modes
by entering a numerical command at the main menu:
At the main menu type 6712.2 to enter extended programming
mode.
At the main menu type 6712.1 to enter standard programming
mode.
RUN “EXTENDED 1”
PROGRAM
VIEW REPORT
OTHER FUNCTIONS
Main Menu for Extended Mode
5.2 One-Part and
Extended programming lets you set up a “one-part” program or a
“two-part” program. One-part programs let you fill all bottles of
the tub with one set of pacing, distribution, and enable settings.
Two-part programs add an additional set of extended pacing, dis-
tribution, and enable screens to the sampling program. Each set
of screens is called a program part. The program parts are simply
called part ‘A’ and part ‘B’. Both parts share the program settings
for suction-line length, suction head, and rinses and retries. They
also share one start-time setting.
Two-Part Programs
5-1
Download from Www.Somanuals.com. All Manuals Search And Download.
6712SR Refrigerated Sampler
Section 5 Extended Programming
Each part has its own group of bottles. Because settings for each
part are independent of each other, the sampler, when running a
two-part program, fills each bottle group as if they were being
filled by two different programs. Two-part programs finish when
both parts are done.
Two-part programming is ideal for sampling storm events. Many
storm-water run-off monitoring permits require a first-flush grab
sample within the first 30 minutes of the storm event and
flow-paced samples during the remainder of the event. With a
two-part program, you can set up part ‘A’ for the first-flush
storm-water sampling program.
5.3 Storage for Extended
Programs
The sampler stores five sampling programs: one standard and
four extended. Program storage eliminates the need to
reprogram the sampler with frequently used settings. This
feature is especially useful for complex extended programs such
as two-part programs or programs with many nonuniform-time
settings.
Teledyne Isco ships the sampler to you with factory programs
that you can modify to suit your own needs. All four extended
programs are identical to each other.
The stored programs will also save your 700 Series Module
program settings and any sampler enable conditions using rain
gauge data or SDI-12 sonde parameters. These program settings
remain as long as you do not change the type of module, or
change the rain gauge or SDI-12 Hardware Setup.
5.3.1 Selecting a Stored
Program
When the sampler is in extended programming mode, it always
has one current and three noncurrent programs, each occupying
a permanent location in memory. The first time you access the
extended mode, the current program is “EXTENDED 1,” one of
the factory extended programs. The name of the current
extended program appears in quotations on the first line of the
main menu.
The factory programs are named “EXTENDED 1,” “EXTENDED
2,” “EXTENDED 3,” and “EXTENDED 4." You can rename them
with more descriptive names, making them easier to identify.
The program name is one of the extended program’s settings.
After selecting a stored program, review the settings with the
quick view screens. Each sampling program stores all the set-
tings required by the sampler to run a program. These settings
include the bottle-kit information (number of bottles and the
bottle volume), the suction-line length, the site description, start
times, and so on.
If you use the same program at two sites — each requiring dif-
ferent bottle configurations, suction line lengths, or other details
— always check these settings before running a program. You
may need to make minor changes to the program to make sure
the settings match your equipment.

6712SR Refrigerated Sampler
Section 5 Extended Programming
The current program is the program you see when you select
PROGRAM from the main menu and page through the pro-
gramming screens. It is the program the sampler uses when you
select RUN from the main menu.
You cannot delete programs, but you can modify them as often as
necessary. To run a program with different settings without
losing the settings in your current program, select a stored
program and modify its settings.
For example, assume you have been running the current
program, named “EXTENDED 1,” at site A for several weeks.
This program contains all the settings you need for site A, and
you don’t want to lose those settings.
Nevertheless, you need another program because you want to
move the sampler to site B, so you select “EXTENDED 2” and
modify it for site B. The settings in “EXTENDED 1” are pre-
served automatically. When you return the sampler to site A, you
won’t need to reprogram the sampler. Merely select
“EXTENDED 1” again, double-check the program settings, and
run the program. To select an extended program, follow the steps
in Table 5-1.

Section 5 Extended Programming
5.4 Programming for 700
series Modules
The bay on the controller’s side accepts any of Teledyne Isco’s 700
Series Modules. These optional accessories are not required to
operate the 6712. However, the modules offer an economical way
to combine flow-rate or parameter monitoring with sampling.
The programming of these modules is integrated with the pro-
gramming of the sampler, so attachment of a module will cause
different screens to be displayed, depending on the type of
module and the selections you make while programming.
Two modules that are commonly used are the 730 Bubbler
Module, which monitors a flow stream’s level and flow rate, and
the 750 Area Velocity Module for monitoring a flow stream’s
level, velocity, and flow rate. Section 4 contains two examples of
programming for modules. Module programming is the same in
Extended as it was in Standard programming.
5.5 Programming SDI-12
Sondes
As an option, the 6712 accepts up to 16 parameters from up to
ten sensors with SDI-12 addresses from 0 - 9. The data param-
eters used by the sonde and sampler must match. Certain
vendors’ sondes, such as Hydrolab and YSI, have enhanced com-
mands that facilitate “plug and play” setup. These Teledyne Isco
Ready sondes can tell the 6712 what values they have, their
order, and units of measure. Other sondes can be used, but
require manual setup to identify proper data types for each data
value reported.
For more information about programming SDI-12 sondes, refer
to Section 6.
5.6 Programming
Examples
In addition to the features available with standard pro-
gramming, and discussed in Section 4, extended programming
offers:
• Nonuniform time pacing
• Random interval pacing
• Event pacing
• Multiple bottle compositing
• Time switched bottles or bottle sets
• Programmable sampler enable
• Pauses and resumes
• Two-part programming
• Automatic or user-defined suction head
• Suction line rinses
• Sampling retries
This manual provides several programming examples. Some,
demonstrating simple tasks, appear in the margins. Others, dem-
the following pages steps you through a storm water runoff sam-
pling using extended programming.

6712SR Refrigerated Sampler
Section 5 Extended Programming
5.6.1 Storm Water Runoff
Sampling
Storm water runoff sampling is an ideal application for two-part
programming. Typical monitoring permits require that a series
of timed samples be taken during the initial portion of the storm
event, followed by flow paced samples during the remainder of
the event.
This example assumes that a Rain Gauge and a Bubbler Flow
Module are connected to the sampler.
Note
To enable the Bubbler Module programming screens, insert
the module before turning on the sampler
Using a 24-bottle kit, it divides the bottles into two groups, with
six bottles assigned to part ‘A’ and 18 to part ‘B.’ The sampler will
begin taking samples after being enabled according to program-
mable enable controls; that is, when the rain gauge detects 0.15
inches of rainfall in 30 minutes, and the module detects a flow
stream level of more than 0.25 feet. Because both program parts
use the same enable settings, the sampler will enable both parts
at the same time. A list of settings for the program follow:
• Program type: Extended.
• Program name: STORM.
• Site description: SITE 54.
• Units: Length – Ft, Flow Rate – gpm, Flow Volume – gal
• Mode of Operation: Flowmeter, Flow-Insert, Round, 12"
• Bottle kit: 24, 1000-milliliter bottles.
• Suction-line length: 5 feet.
• Suction head: Auto suction head.
• Line rinses: None.
• Sampling retries: None.
• Part ‘A’ and ‘B’ bottle assignments: Bottles 1 - 6 to part
‘A’, bottles 7 - 24 to part ‘B’.
• Part ‘A’ pacing: Time pacing, sampling every 5 minutes.
• Part ‘A’ distribution: Sequential, 1 sample per bottle.
• Part ‘A’ sample volume: 800 milliliters.
• Part ‘A’ enable: At least 0.15 inches of rainfall in 30
minutes and a flow stream level of more than 0.25 feet;
once enabled, stay enabled, sample taken when the
sampler is enabled.
• Part ‘A’ pause and resumes: None.
• Part ‘B’ pacing: Flow pacing, sampling every 2,500
gallons.
• Part ‘B’ distribution: Sequential, 1 sample per bottle.
• Part ‘B’ sample volume: 500 milliliters.
• Part ‘B’ enable: At least 0.15 inches of rainfall in 30

During a line rinse cycle, the sampler draws liquid through the
line to the liquid detector. As soon as it detects liquid, the
sampler reverses the pump to purge the line.

5.9 Pacing
Sample pacing is the rate at which the sampler takes samples.
Depending on the type of pacing you select, the rate is controlled
by the sampler’s internal clock or by inputs received from con-
nected instruments.

NONUNIFORM TIME
Standard programming provides time pacing and flow pacing,
which are described in Section 4. Extended programming pro-
vides additional pacing types, so its pacing screen (see example
in margin) has four items listed instead of two.
“Uniform time” pacing is identical to “time” pacing in standard
programming. “Flow paced” is the same for both types of pro-
gramming. Event paced and nonuniform time pacing are
described below.
5.9.1 Event Pacing

uses three event conditions.
Up to fourteen event conditions can be defined (for two-part pro-
grams, up to fourteen event conditions can be defined for each
part). An event will occur when any of the programmed event

conditions becomes true. The default distribution setting for
event-paced sampling is sequential (each time an event occurs,
the sampler takes one sample, placing it in one bottle). However,
any distribution setting may be used.
If you have programmed multiple conditions, and more than one
condition comes true at the same time (within your measurement
interval), one sample will be taken and all conditions that caused
the event will be noted on reports.
Although you can combine flow pacing and all time pacing types
with any distribution, event paced programs by definition use
only sequential distribution. The sampler finishes an event
paced program after depositing a sample in each bottle.
7). This feature enables the event condition under specific cir-
cumstances.
In the example below, a rate of change is set so that if the level
rises more than one foot in a two hour time period, the event con-
dition would be enabled and a sample taken.
In determining if the rise occurs in this example, the sampler
looks back at the previous two hour time period to see if there is
a rise of more than one foot between any valley (low point) or
peak (high point) within that time period.
Once the condition becomes true (a rise of more than one foot is
noted), the event condition is enabled. It will not be enabled
again unless the condition becomes false, and then true again,
within the two hour time window.
In event pacing, up to three different rate of change event condi-
tions can be programmed (for two-part programs, a total of six
rate of change event conditions can be defined, three for each
part).
5.9.2 Event Paced Sampling
This example uses a sampler with an attached 730 Bubbler Flow
Module, Rain Gauge, and an SDI-12 sonde at address 5 with four

5.9.3 Nonuniform Time
Pacing
The extended time pacing options are uniform time and non-
uniform time. “Uniform time” pacing is identical to “time” pacing
in standard programming. Nonuniform time pacing uses an
irregular interval between sample events; each interval is indi-
vidually programmable. There are three types of nonuniform
time pacing:
• Nonuniform clock time pacing.
• Nonuniform interval pacing.
• Random interval pacing.
5.9.4 Nonuniform Clock
Time Pacing
For clock time pacing, enter specific times for each sample event
(see screen 2). You can enter as many as 99 clock times, but the
interval between times cannot be greater than 24 hours.
(Remember to use a 24-hour clock when entering times.) The
sampler takes a sample at the start time.
5.9.5 Nonuniform Interval
Pacing
For nonuniform interval pacing, enter the number of sample
events spaced at intervals of minutes: 12 samples at 5 minute
intervals, 6 samples at 10 minute intervals, and so on. The
sampler accepts as many as 99 nonuniform interval entries. The
sampler takes a sample at start time.
5.9.6 Random Interval
Pacing
To program the sampler for random interval pacing, enter the
length of time you want to sample. The run time is the only
random programming setting you’ll need to enter because the
sampler derives the number of sample events required for the
program from the distribution settings. (You can combine
random pacing with any distribution.) Each time you run the
program, the sampler generates a new set of random intervals.
This makes each sample event unpredictable from run to run.

Section 5 Extended Programming
5.10 Distribution
Distribution describes how the sampler is to deposit samples. A
sample is the volume of liquid deposited in a bottle. A sample
event includes the full sampling cycle and may deposit a sample
into more than one bottle. You can program the sampler for five
distribution methods:
• Sequential
• Bottles per sample
• Samples per bottle
• Composite
• Multiple Bottle Compositing
5.10.1 Sequential
In sequential distribution, the sampler deposits one sample in
each bottle. A sequential sample represents a “snapshot” of the
flow stream at a point in time.
5.10.2 Bottles Per Sample
In bottles per sample distribution, the sampler deposits a sample
in each of a set of bottles. A bottle set includes at least two bottles
but may include all bottles. Use bottles per sample when the
volume to be collected is larger than the amount one bottle can
hold or when you need identical samples.
5.10.3 Samples Per Bottle
5.10.4 Composite
In samples per bottle distribution, the sampler deposits samples
from several sample events in a single bottle before moving to the
next bottle. Use samples per bottle distribution to collect a series
of small composite samples.
For single bottle configurations, samples per bottle distribution
is known as composite sampling. A composite sample represents
an average of the flow stream’s characteristics during the sam-
pling period.
5.10.5 Multiple Bottle
Compositing
Multiple bottle compositing is a combination of
bottles-per-sample and samples-per-bottle. At each sample event,
the sampler deposits a sample into a set of bottles. It moves to a
new bottle set only after each bottle of the first set contains the
programmed number of samples. Use multiple-bottle compos-
iting to collect identical sets of composite samples or a composite
sample that is larger than the capacity of a single bottle. Mul-
tiple bottle compositing is available only in extended pro-
gramming.
5.10.6 Time Switching
In extended programming, the sampler offers an additional dis-
tribution feature, time switching. This feature determines when
the sampler fills the next bottle or bottle set, and may be used
with time-paced or flow-paced sample programs. Time switching
distribution occurs at regular intervals (as programmed in
screen 3 in the margin). The switch times are relative to the pro-
grammed “FIRST SWITCH TIME” (screen 4).
Switch times occur regardless of the state of the sampler. Be
aware that the sampler may leave empty bottles if it becomes
disabled. Pause and resumes are an exception; the sampler will
not switch bottles during a pause if the current bottle is empty.

6712SR Refrigerated Sampler

If the program settings instruct the sampler to take a sample at
the start time, the sampler also draws a sample at the switch
time. When this occurs, the pacing will also be reset at the switch
time.

Time switching is normally used with flow-paced programs that
do not take a sample at start. These programs will place a
sample in the current bottle if it is empty at the switch time, and
then move to the next bottle/set. Pacing intervals are reset at
every switch time.

5.10.7 Continuous Sampling
Sample programs can be run indefinitely by selecting “YES” at
the “RUN CONTINUOUSLY?” screen. Continuous sampling
resets the distribution when the distribution sequence is com-
plete. That is, when the last bottle/set is reached, the next
bottle/set is the first bottle/set. All pacing modes except
RANDOM are supported.
When running a program continuously, the bottles must be ser-
viced at regular intervals to prevent overfilling the bottles. The
sampler assumes that the next bottle/set is empty and ready to
receive samples. If you are using this feature with two-part pro-
gramming, keep in mind that the parts will most likely reset at
different intervals.

5.11 Flow Proportional
Sample Volumes
The 6712 can collect flow proportional sample volumes. For some
sampling protocols, these flow-weighted, variable-volume
samples can be more representative of the stream. This is
because stream characteristics often change as the flow fluc-
tuates.
Variable-volume sampling is possible when the sampler is pro-
grammed for Uniform Time pacing. To enable this feature, select
YES at the display asking “DO YOU WANT SAMPLE
VOLUMES DEPENDENT ON FLOW?”
DO YOU WANT
SAMPLE VOLUMES
DEPENDENT ON FLOW?
YES
NO
After answering YES, the sampler displays screens to program
the flow proportional volumes. If the sampler has a 700 Series
Flow Module inserted, you will be asked which flow mea-
surement should be used to determine the volumes.
FLOW PULSES
FLOW MODULE VOLUME
To base the volumes on an external flow measurement device
attached to the Flow Meter connector, select FLOW PULSES. To
base the volumes on the 700 Series Flow Module readings, select
FLOW MODULE VOLUME.
Next, the sampler asks for the SAMPLE VOLUME to collect at
each time interval. This volume is expressed as 10 ml for every X
number of pulses, or if using a flow module, for every volume
unit.

10 ml FOR EVERY

tings, for a more detailed discussion on this setting.
The final screen used to program variable-volume sampling is
the MINIMUM SAMPLE VOLUME. If the number of flow pulses
or flow module volume is not sufficient enough to collect this
minimum volume, the sample is skipped and the flow count
carries over to the next sample time. This setting ranges from
10 ml to a maximum determined by the bottle volume.

5.11.1 Calculating Variable
Sample Volume
Settings
The entry for the SAMPLE VOLUME display can be calculated
based on expected flow rates and collection volume requirements.
The number of pulses or flow module volume that you enter
should ensure that the minimum volume of liquid required for
analysis is collected without exceeding the bottle volume capacity
of the sampler. You may find it helpful to determine a range of
values by calculating both possibilities. The number you enter
would be selected from this range. This range is illustrated in
Total Bottle
Capacity
Minimum
Required Sample
Volume
Time
Figure 5-2 Factors Affecting Flow-Weighted Variable-Volume Samples
In other words, at the greatest expected flow, this SAMPLE
VOLUME value should be set to prevent filling the bottle before
the end of the program. An early full-bottle condition would
result in a composite sample that is not representative of the
flow stream.
At the lowest expected flow, the SAMPLE VOLUME value should
be set to ensure that enough sample is collected. If too little
sample liquid is collected, there may not be enough for analysis
although it is a representative composite sample.
For example, consider an NPDES sampling program used to
collect a flow-proportional composite sample for BOD, TSS, and
NH -N analysis. The laboratory requires at least 1,000 ml for
3
BOD, 100 ml for TSS, and 400 ml for NH -N tests. The minimum
3
composite volume needed for analysis is then 1,500 ml, but to
allow for duplicates and spillage, this volume is doubled to
3,000 ml. The samples are to be collected over an eight hour
period at 15 minute intervals into a 9,400 ml composite bottle.
Flow rates at the site range from 1.5 to 2.0 mgd, the equivalent
volume of 500,000 and 666,667 gallons respectively over the
eight hour period. This flow is measured by an external flow
meter that sends a flow pulse every 100 gallons. Figure 5-3
depicts this scenario.

5.11.2 Calculations when
The highest possible SAMPLE VOLUME value is determined by
Using an External Flow the minimum volume required for analysis and the least
Meter
expected flow rate over the sampling duration. To calculate the
number of pulses at this high end of the range, you should know:
• the least expected flow volume that will pass the flow
measurement point
SAMPLE VOLUME:
10 ml FOR EVERY
___ PULSES
• the flow volume interval between each flow pulse from
the external flow meter
• the minimum composite sample volume required for
analysis. Allow for duplicates and spillage.
These factors would be applied to the following equation.
(Least Total Flow Vol) / (Flow Pulse Vol)
=
10 ml for every __ pulses
(Minimum Required Vol) / (10 ml per unit)
From the scenario we can apply the factors for the equation.
(500,000 gallons) / (100 gallons per pulse)
=
10 ml for every 16.7 pulses
(3,000 ml / 10 ml)
Because the SAMPLE VOLUME entry must be in whole
numbers, 16.7 is rounded down to 16. It is important to note that
this number is inversely proportional to the amount of volume
collected. Rounding up would result in less volume collected.
The lowest possible SAMPLE VOLUME value is dependent upon
the highest expected flow and the available bottle volume. To cal-
culate the number of pulses or volume at this low end, you should
know:
• the greatest expected flow volume that will pass the flow
measurement point
• the flow volume interval between each flow pulse from
an external flow meter
• the available bottle volume for sample collection.

These factors would be applied to the following equation.
(Greatest Total Flow Vol) / (Flow Pulse Vol)
=

(Total Bottle Vol) / (10 ml per unit)
From the scenario we can apply the factors to the equation.
(666,667 gallons / 100 gallons)
=
10 ml for every 7.0 pulses
(9,400 ml / 10 ml)
At high flow rates, a number below 7 would overfill the bottle. At
low flow rates, a number greater than 16 would collect too little
sample. Therefore, a value should be selected between 7 and 16
pulses.
5.11.3 Calculations when
Using a 700 Series Flow the equations differ slightly because the flow module directly
Module
measures the stream’s flow volumes. The equation for the high
end of the range is:
(Least Total Flow Vol)
=

(Minimum Required Vol) / (10 ml per unit)
Using the same scenario the calculations would be:
SAMPLE VOLUME:
10 ml FOR EVERY
___ Gallons
500,000 gallons
=
10 ml for every 1667 gallons
(3,000 ml) / (10 ml per gallon)
The equation for the low end of the range is:
(Greatest Total Flow Vol)
(Total Bottle Vol) / (10 ml per unit)
=
10 ml for every __ units
The scenario would be applied as:
666,667 gallons
=
10 ml for every 709 gallons
(9400 ml) / (10 ml per unit)
Therefore, a value should be selected between 709 and 1667
gallons for the given scenario.
5.12 Sampler Enable
Certain external instruments can enable (start) or disable (stop)
a sampler by sending a signal to pin F of the sampler’s flow
meter connector. Teledyne Isco flow meters, flow loggers, and the
Teledyne Isco 1640 Liquid Level Actuator have a programmable
sampler-enable feature that lets them enable or disable the
sampler. You can define the condition (such as level, flow rate,
pH, temperature, percent, rainfall, and I/O) or combination of
conditions that need to be true in order to enable the sampler.

Section 5 Extended Programming
5.13 Sampler Enable
Responses
In addition to programming enable conditions, extended pro-
gramming lets you control the sampler’s response to its enable
state. You can:
• Stay enabled after the first enable.
• Set up a repeatable enable.
• Take a sample at enable or disable.
• Delay the start of sampling after the enable.
• Reset the sampling interval countdown each time the
sampler is enabled.
• Control the sampling interval countdown while
disabled.
• Enable Part B of a two-part program when Part A is
done.
5.13.1 Once Enabled Stay
Enabled
For certain monitoring programs, you may want the sampler to
continue to sample, even though the conditions that enabled the
sampler no longer exist. When you use the ONCE ENABLED,
STAY ENABLED feature, after becoming enabled the sampler
takes samples until it reaches the end of its program.
ONCE ENABLED,
STAY ENABLED?
YES NO
Note
The STAY ENABLED feature works only when the sampler
becomes enabled following program start. If you need this fea-
ture with enable prior to program start, contact Teledyne Isco
for details.
5.13.2 Repeatable Enable
After enabling the sampler, the enabling instrument (or instru-
ments) continues to monitor the conditions and disables the
sampler when the conditions are no longer satisfied. If
re-enabled, the sampler resumes the sampling program.
Note
Repeatable enable is called “sampler latching” in flow meters,
flow loggers, and FLOWLINK. Latching a sampler produces
the same results as selecting YES; the difference is that the
external instrument controls the latching.
5.13.3 Sample at Enable or
Disable
You have the option of directing the sampler to take a sample as
soon as it receives the enable and/or disable signal. If you
program the sampler to stay enabled and choose to take a sample
at enable, the sample interval will be reset at the enable time.
Samples at disable do not affect the sample intervals. Standard
programs do not take a sample at the enable time.
SAMPLE AT ENABLE?
YES NO

Section 5 Extended Programming
5.13.4 Delay To Start Of
Sampling
If you have selected ONCE ENABLED STAY ENABLED and
have chosen to not sample at the enable, you have the oppor-
tunity to suspend the start of sampling. This choice is useful for
storm programs that require a flow-paced sample taken after the
initial grab sample.
START SAMPLING
AFTER A
___ MINUTE DELAY
(1-999)
5.13.5 “Dry Period” Option
For samplers used with a 0.01 inch tip rain gauge, you can cause
the sampler to wait for a “dry” period of under 0.10 inches of rain
over a 72-hour period before running the program. At RUN time,
the sampler asks if you want to restart the 72-hour period. Select
this choice if you want the sampler to disregard any “dry” period
that took place prior to the program start. The sampler will wait
for up to one year for the “dry” period to occur.
START “EXTENDED 1”
AFTER A 72 HOUR
“DRY” PERIOD?
YES NO
5.13.6 Resetting the Sample
Interval at Enable
You may want the pacing countdown to start over each time the
sampler becomes enabled. To accomplish this, select “YES” when
asked if you want to reset the sample interval at enable. The next
sample event will occur at the end of a full interval. Fur-
thermore, if the sampler is enabled several times during the
program, it resets the countdown each time.
RESET SAMPLE
INTERVAL AT ENABLE?
YES NO
If you answer “NO” to the above
screen, you will see:
Use the reset-interval feature carefully. For example, avoid
resetting the interval when you sample with uniform-time
pacing and want to take samples at specific times.
CONTINUE COUNTDOWN
WHILE DISABLED?
YES NO
The effects of resetting the interval can be seen in this example:
A sampler has been programmed to sample every 15 minutes and
to reset the interval when enabled. It receives an enable signal at
10:03 and takes a sample. After resetting the interval, the
sampler takes subsequent samples at 10:18 (not 10:15), 10:33
(not 10:30), and so on.
If you select “NO” when asked if you want to reset the sample
interval at enable, you will be asked if you want to continue the
countdown while disabled. You can have the sampler continue
the countdown, repeating it as often as necessary while the
sampler is disabled, or you may suspend the countdown while
disabled, resuming the countdown as the sampler is enabled. The
standard program allows the countdown to continue while dis-
abled.

6712SR Refrigerated Sampler
Section 5 Extended Programming
5.14 Pauses/Resumes
Pause and resume settings, available in extended programming,
create an intermittent sampling schedule. A program with
pauses and resumes begins sampling at its programmed start
time, continuing until the first pause time and day of the week. It
then suspends sampling until the first resume time, when it
begins sampling again. If the start time falls within a pause
period, the sampler will not begin sampling until the next
resume time. Pauses and resumes repeat weekly.
Pause and Resume Screens
Flowcharts containing the pause and
resume screen appear in Appendix
A.
PAUSE
RESUME
1. 17:00 MO 08:00 TU
2. 17:00 TU 08:00 WE
CLEAR
DONE
You can enter up to nine pairs of pause and resume times. The
pause and resume times shown as examples to the left suspend
the program between 5:00 p.m. Monday and 8:00 a.m. on
Tuesday and between 5:00 p.m. Tuesday and 8:00 a.m. on
Wednesday. If the start time is Monday at 8:00 a.m., the sampler
takes samples between 8:00 a.m. and 5:00 p.m. Monday; between
8:00 a.m. and 5:00 p.m. Tuesday; and, continues after 8:00 a.m.
Wednesday. To remove pause and resume settings from a
program, select CLEAR.
SAMPLE AT RESUME?
YES NO
A sampler running a pause/resume program resets the pacing
interval at each resume time. You can program the sampler to
take a sample at resume times (see screen at left).
5.15 Running Programs
To run an extended program, select run from the main menu.
You may also select YES at the RUN THIS PROGRAM NOW?
screen at the end of the programming screens.
Extended programs scheduled to start at a clock time will not
start until the programmed clock time on or after the first valid
date.
Note that if you have recently calibrated a parameter probe, the
sampler may delay the start and display “PLEASE WAIT” until
valid readings are expected from the probe. The delay accounts
for the time typically required to install the probe, and lasts for
five minutes after you complete the calibration.
5.15.1 Run Time Screens
Run time screens, which report the program’s status while
running a program, are explained in Section 4.
5.15.2 Interrupting a
Running Program
Interrupting a running program is also explained in Section 4.
The scrolling menu that appears during the manual paused state
can have two extra options when using extended programming:
Adjust Enable – This option is available for extended sampling
programs that have programmed enable conditions. Selecting
this option allows you to change the set-points or ranges for the
enable conditions. The sampler displays all of the programming
screens that define the thresholds of the programmed enables.
You cannot change the type of enables used or the way they are
combined.
If rain is an enabling condition, you also have the option of
resetting the rain history.

Adjust Suction Head – If you have chosen to manually enter
the suction head, and are in the manual paused state, the
scrolling menu will have an option to adjust the suction head. If
you make changes to the suction head value, the sampler logs a
changed suction head event.
5.16 Sampling Reports
The 6712 records a variety of data while running a sampling
program. Sample reports can be found in Section 4.

5.18.2 Programming Style
The sampler has two different styles of programming screens:
normal and quick view. These are both explained in Section 3.
When you are in extended programming, the default style is
Quick View, which allows you to move more quickly through the
screens.
If you prefer a step-by-step display for the screens, switch to the
Normal setting.
5.18.3 Measurement Interval
If using a 700 Series module or SDI-12 Sonde parameter for
enabling, the sampler will request a Measurement Interval. The
Measurement Interval allows the sampler to compare the
parameter to the enabling conditions at a rate faster than the
Data Storage interval. If the Measurement Interval is equal to or
greater than the Data Storage interval, the parameter will be
checked at the rate of Data Storage interval.
MEASUREMENT INTERVAL
5
1
15 30 SECONDS
2
5
MINUTES
STORAGE INTERVAL
Normally, there are two considerations when selecting the Mea-
surement Interval: power consumption and duration of the
enabling event. This setting for battery powered samplers will
require some degree of balance between the need to conserve
power yet detect the enabling event before it has passed.
5.18.4 Dual Sampler Mode
Dual Sampler Mode lets you operate two samplers as a pair. The
primary sampler disables the secondary one until the primary
sampler completes its sampling program. The samplers then
reverse roles with the second sampler becoming the primary one.
Dual Sampler Mode
DUAL SAMPLER MODE?
YES NO
Setting Up Dual Samplers –
1. Turn on the dual sampler mode in both samplers.
2. Install the samplers.
• Select YES to put the sampler
in the dual sampler mode.
When you no longer need
dual samplers, return to this
screen to turn the feature off.
3. Connect the samplers with the Dual Sampler Mode Inter-
connect Cable by attaching the cable to the sampler’s
flow-meter connectors. If your installation includes a flow
meter or flow logger, use the Dual Sampler Mode to Flow
Meter Cable instead.
4. Decide which sampler is to be the primary sampler; the
primary sampler should be the sampler with the program
you want to run first.
5. Turn the primary sampler on and run its sampling pro-
gram by selecting RUN. After at least 5 seconds, turn the
secondary sampler on and select RUN from its main menu.
How Does It Work? – The primary sampler sends a disable
signal out its flow meter connector. The secondary sampler
receiving the signal is held disabled until the primary sampler
completes its program.
When using a flow meter or flow logger a Dual Sampler Mode to
Flow Meter cable must be used. This cable is constructed so that
the pacing instrument receives only the event marks. Therefore,
a connected flow meter will not receive a bottle number signal,
nor will it be able to control the sampler inhibit.

6712SR Refrigerated Sampler
Section 5 Extended Programming
Bottle Full Detection – The sampler can detect a full bottle
condition when collecting samples in a single bottle (composite
sampling). When the sampler detects a full bottle, it stops the
sampling routine.
Bottle Full Detect
BOTTLE FULL DETECT?
YES
NO
A BOTTLE FULL condition will also stop a sampling routine
that is set to RUN CONTINUOUSLY.
The Bottle Full Detect screen allows you to enable or disable this
feature. Selecting “YES” enables the sampler to detect a full
bottle and stop the sampling routine. Selecting “NO” disables
this feature. The Bottle Full Detect setting is part of the sam-
pling program. Because it is a program setting, full bottle
detection can be enabled or disabled for each of the four extended
programs. If the Bottle Full Detect setting is critical to your sam-
pling program, always check this Software setting after you
select a different Extended Program.
This feature relies on a post-purge after each sample. When
using the Bottle Full Detect, make sure that post-sample purges
greater than 100 are used.
Bottle Full Detect is always disabled in the Standard Pro-
gramming mode.
Display Backlighting – The display has a backlight that is
adjustable so that the backlight is always off, timed or always on.
Adjusting the Display
Backlighting
In the timed backlight mode the sampler turns the backlight off
after detecting no key strokes within 60 seconds. Any keystroke
(except ON-OFF) turns the backlighting on again. In this mode
the backlight must be on before the sampler accepts a menu
choice or number entry. If you press a key and a screen does not
respond, it is because the keystroke turned the backlight on.
BACKLIGHT ALWAYS OFF
TIMED BACKLIGHT
CONTINUOUS BACKLIGHT
It is recommended that you use either BACKLIGHT ALWAYS
OFF or TIMED BACKLIGHT when using a battery.
Event Marks – The sampler generates an event mark at each
sample event, sending it through the flow meter connector to a
connected instrument. The event mark may also control an
external device; a connected solenoid relay, for example. When
using the event mark for a data logger or to control external
devices, you may need to adjust the mark by changing the factory
settings.
Event Marks
EVENT MARK SENT FOR:
EVERY SAMPLE
COMPLETE SAMPLES
The event mark is adjustable through the software setup screens.
You can set up the sampler to generate an event mark for
EVERY SAMPLE or for COMPLETE SAMPLES.
If you select COMPLETE SAMPLES, the sampler sends a
three-second pulse only after it successfully collects a sample.
The sampler will not send an event mark if an error occurs, such
as “No Liquid Detected.”
If you select EVERY SAMPLE, the sampler will send an event
mark every time a sample is initiated. The event mark signal can
be a:
• 3-second pulse at the beginning of the pre-sample purge.

only, marking the time the sampler deposited the
sample.
• Variable duration pulse generated during the pump
cycle, from the beginning of the pre-sample purge to the
end of the postsample purge.
• Variable duration pulse generated only during forward
pumping.
Bottle Number – Concurrent with the event mark, the sampler
also sends a bottle number signal. The bottle number signal is a
series of pulses. The number of pulses sent represents the bottle

5.18.5 Pre-sample and
Post-sample Purge
Counts
The pre-sample purge is when the pump runs in reverse clearing
the strainer of any debris before taking a sample. The pre-sample
purge is set at 200 pump counts. After the sample is taken a
post-sample purge occurs to clear the liquid from the suction line.
The duration of the post-sample purge is determined by the
length of the suction line to maximize the battery life. The pre-
and post-sample purge can also be manually set.

5.19.3 I/O Pin Programming
Pins C, H, and I on the Rain Gauge Connector are user-con-
figured as I/O1, I/O2, and I/O3 (Input/Output pins) respectively.
Each pin can be either an input for sampler enabling, or an
output for alarms.
Note
The state of the I/O lines is not defined when the sampler is
OFF.
The enable input requires a pulse signal of 5 to 15 volts. Teledyne
Isco offers optional interface modules for converting from a 4-20
mA analog or pulse duration signal.
The alarm output can be set for any RUNNING PROGRAM or
RUN ERROR state. In addition, the CONDITIONS output can
report alarm conditions using the parameters the 6712 is con-
figured to measure. You can set thresholds for one or two condi-
tions and the CONDITIONS output can then trigger alarms
when the measured parameters exceed the threshold.
The alarm output requires an alarm interface module. Teledyne
Isco offers a module designed to provide one, two, or three
contact closures. The alarm module can interface the sampler
with a large number of non-Teledyne Isco devices. For more infor-
mation about the alarm module, contact your Teledyne Isco sales
representative.
5.19.4 Refrigerator
Temperature
Teledyne Isco offers a temperature sensor intended for use with
the 6712FR Refrigerated Sampler. The optional sensor connects
to the Rain Gauge port and uses I/O3 to transmit its temperature
readings to the 6712.
Note
If alarms are being used, the temperature sensor is simply
plugged into the panel mount on the one- or two-alarm output
module. Because the temperature sensor uses I/O3, it cannot
be used with a three-alarm output module.

6712SR Refrigerated Sampler
Section 5 Extended Programming
To configure an attached temperature sensor, select “FR-TEMP”
as the input for I/O3. The 6712 will display the NEW
HARDWARE SETUP screen. Select DONE and the 6712 recon-
figures its memory partitions to record the temperature
readings.
Temperature readings are updated approximately every 2.5
seconds. The readings are stored as FR-TEMP readings at the
data storage interval. You can retrieve a history of temperature
readings through the 6712’s reports. The temperature data also
can be used as a sampler enable condition.
5.19.5 Analog Output
Teledyne Isco offers multiple analog outputs as a factory
installed option. The number of isolated outputs can vary from
one to three and is specified at order time. The option is installed
inside the controller and includes a six-pin connector to interface
with external devices.
The analog outputs can be programmed for either 0-to-20 mA or
4-to-20 mA operation. With the exception of rain, any parameter
that the 6712 sampler is currently measuring can be used to
control any (or all) of the analog output channels. Programming
the outputs requires parameter levels at each end of the analog
range and then assumes a linear relationship between those
points. MANUAL CONTROL of each output is also available.
Flowcharts for analog output screens appear in Appendix A.
5.19.6 Dialout Alarms
Dialout alarms require the sampler to be equipped with the
factory-installed 2400 baud talking modem. The dialout alarm
allows the sampler to notify a contact list when an “alarm” con-
dition exists (is true).
At the transition to the true state, any programmed I/O output
can cause the sampler to warn of the alarm condition. As many
as three telephone numbers can be entered. The sampler tries
each telephone number in succession until the alarm is acknowl-
edged. For each alarm condition, the sampler will attempt each
telephone number entered a maximum of five times, at user spec-
ified intervals.

Extended characters, the Comma (,), Pound (#), and Star (*), also
may be included in the 25 digits. To enter an extended character,
press the Decimal Point key on the Avalanche keypad. The Ava-
lanche displays a screen used to select and enter the extended

Dialout telephone and pager numbers are included in the
Program Settings Report.
Note
Connecting either the serial output or the standard interrogator
cable to the Avalanche disables the internal dial-out modem.
The interrogator or serial output cable must be disconnected
before you can use the modem.
5.19.7 Pager Numbers
The extended character screen contains a pager option that des-
ignates the phone number as a pager. When programmed as a
pager number, an identification string will be sent seven times
after the pager number is dialed, with a three second delay
between strings.
An example identification string would be “828-1”, meaning
“Alarm condition #1 exists at sampler 828”. If more than one
alarm condition exists, the string would read similar to “828-1-3.
5.19.8 Digital Modem Text
Messaging
The sampler can also send alarms in the form of text messages
containing the same information as that found in voice messages.
To use this option, you must have:
• a cellular phone with text messaging capabilities
• an external digital modem
recommended: Teledyne Isco’s AnyDATA modem
part # 60-5314-489
Note
If an internal voice modem is installed, the sampler will use
that modem, and text messaging will be disabled.

cations parameters will be made.
As with voice messaging, the sampler will dial each telephone
number up to five times per alarm condition, until the message is
acknowledged.
5.20 Memory
The 6712 Sampler contains 512 kilobytes of battery backed RAM
(Random Access Memory) that stores:
• Five sampling programs
• The sampling results from the most recent program
• The rainfall data collected from rain gauges
• The data from a refrigerator temperature sensor
• The data collected from a 700 Series module
• Parameter data collected from an SDI-12 Sonde
• Calculated flow information from the current flow
module
The sampling results memory stores up to approximately 1004
events (the actual number is dependent on the number of SDI-12
parameters). The program run and start time information is
logged as four events. These four entries are held for the duration
of the program. The remaining 1000 are for logging sample
events, program events, and errors from the currently running
program. If the running program exceeds 1000 events, the data
will “roll over.” That is, the sampler will replace the oldest stored
event with the newest event. When using an SDI-12 sonde, the
sampler logs additional entries at each sample event.
Module, sonde, refrigerator temperature, and rain gauge
readings are stored in memory partitions. The storage capacity
depends on the reading types, the number of bytes per reading,
and the data storage interval.
The sampler clears the sampling results memory when the site
description changes. It is important to collect the sampling
results before changing the site description – the data can not be
retrieved afterwards. Keep in mind that the description may
change when selecting an extended program.
The partition data is cleared when the sampler automatically
creates and sizes the memory partitions. This occurs when you:
• Select a new program with a different storage interval
• Change the Data Storage Interval in the current
program
• Change the programming mode
• Install a new 700 Series Module
• Change 700 Series Module mode of operation
• Add or remove a rain gauge with the Hardware Setup
• Add or remove a refrigerator temperature sensor as I/O3

6712SR Refrigerated Sampler
Section 5 Extended Programming
• Add or remove a SDI-12 sonde parameter with the
Hardware Setup
• Reinitialize the sampler
The stored data is lost as the sampler reformats its memory. As a
precaution, before clearing the memory, the sampler display will
show the following message:
INTERVAL CHANGED --
DOWNLOAD DATA NOW
OR LOSE ALL DATA!
DONE
If you want to keep the stored data, download it before pro-
ceeding. When DONE is selected, the sampler clears the stored
data and reformats the memory partitions. The sampler then dis-
plays the new capacity of the partition memory.
PARTITION MEMORY
WILL LAST 13 DAYS
If the duration is too short, try changing the data storage
interval or eliminating unnecessary reading types in the
Hardware or Module Setup. For example, a sampler configured
with a 730 Bubbler Module and a rain gauge storing data at a
one-minute interval, creates level and rainfall partitions that
hold 100 days of readings. Changing the storage interval to two
minutes extends the storage capacity to 201 days.
The sampler does not have to be running a program to store
readings. When the sampler is on, it stores readings at the
selected data storage interval. Once the partition is filled, the
readings roll over.
When the sampler is running a program, the partitions become
“triggered” by the programmed start time or the first enable
time, whichever is later. A triggered partition continues to log
readings at the selected interval, but will not replace any
readings taken after the trigger event. The sampler fills the par-
tition and then stops recording to preserve the data. The first
reading preserved in a full partition is one hour before the
trigger event. A full partition can be reset by starting another
program or changing storage parameters.
If you need continuous readings for analysis, be sure to collect
the readings before the partition fills or rolls over to avoid gaps
in the data.
5.21 Pressurized Lines
The sampler can obtain samples from pressurized lines, as long
as the line pressure remains below 15 PSI (pounds per square
inch). Pressures greater than 15 PSI may prevent the sampler
from purging the suction line; moreover, extreme pressures can
force liquid past the pump, even when the pump is not running.

6712SR Refrigerated Sampler
Section 5 Extended Programming
For more consistent sample volumes from lines under constant
pressure, calibrate the samples. Teledyne Isco does not rec-
ommend sampling from pressurized lines.
5.22 Command Driven
Operation
The 6712 controller can be used as a slave to an external con-
troller. The external controller is responsible for determining
when to take a sample, how much volume to pump, and where to
put the sample. The external controller directly interfaces to the
sampler via an RS-232 communications port at 2,400-19,200
baud, 8 data bits, no parity, and 1 stop bit. A comma-sepa-
rated-value protocol is used by the external controller to make
requests, and by the sampler to report results. Use a standard
computer connect cable (see Appendix E) to connect the sampler’s
interrogator port and the external controller.
For information on serial data codes and their meanings, refer to
The 6712 Sampler will respond to three commands: Turn
Sampler On, GET STATUS, and TAKE SAMPLE. All commands
must include the instruction set. The checksum value is optional.
The available commands are:
1. Turn Sampler On: STS,2,CS,582<CR>
• “582” is the byte-by-byte sum of the ASCII values in the
string “STS, 1,CS”.
• “<CR>” is a carriage return signifying the end of the
command.
• If the sampler is OFF, this command will turn it ON
before returning status info.
2. Get Status: STS,1,CS,581<CR>
“STS,1” instructs the sampler to return the current status.
• “CS,581” is the optional checksum value. The
byte-by-byte sum of the ASCII values in the string
“STS,1,CS” is 581.
• “<CR>” is a carriage return signifying the end of the
command.
3. Take Sample: BTL,2,SVO,100,CS,1039<CR>
The TAKE SAMPLE command is only valid if the sampler is
WAITING TO SAMPLE.
• “BTL,2” instructs the sampler to place the sample in
bottle 2.
• “SVO,100” instructs the sampler to take a 100 ml
sample.
• “CS,1039” is the optional checksum value. The
byte-by-byte sum of the ASCII values in the string
“BTL,2,SVO,100,CS,” is 1039.
• “<CR>” is a carriage return signifying the end of the
command.

6712SR Refrigerated Sampler
Section 6 SDI-12 Sondes
In order to provide you with the flexibility to use the water
parameter sensors that best meet your needs, Teledyne Isco has
implemented support for SDI-12 protocol. Support of this
standard allows you to use SDI-12 compatible devices in con-
junction with your 6712SR sampler in Extended Programming
mode.
6.1 SDI-12 Data
Parameters
The 6712 Sampler can accept up to 16 parameters from up to ten
sensors with SDI-12 addresses from 0 - 9 (refer to chart in Figure
6-1). This data can be used in different ways. Data can be logged
at user selectable time intervals for later download and pro-
cessing by Teledyne Isco’s Flowlink™ program. You can set up
sampling programs that will be enabled to run only if conditions
based on parameters monitored by the connected SDI-12 devices
are met. The sampler can also be programmed to take samples
each time certain parameter limits are exceeded.
The data parameters used by the sensing device (sonde) and
recording device (sampler) must match. Otherwise, the
equipment could record the data values for one parameter as
another’s, such as reporting a pH value as being temperature.
Certain vendors’ sondes (such as Hydrolab and YSI) have
enhanced commands that facilitate “plug and play” setup. These
Teledyne Isco Ready sondes can tell the 6712 what values they
have, their order, and units of measure.
Other SDI-12 compatible sondes can be used, but require manual
setup to identify proper data types for each data value reported.
This section shows you how to set up both Teledyne Isco Ready
and other SDI-12 sondes for use with the 6712.
WARNING
SDI-12 Sondes have not been approved for use in
hazardous locations as defined by the National Electrical
Code.
CAUTION
Before you install any sonde, you must take the proper safety
precautions. Refer to Appendix C in the back of this manual.
Additional safety considerations may be required. Check appli-
cable guidelines, codes, and regulations of federal, state, city,
and county agencies.

6.5 Sonde Setup - Storing
Parameter Data
Whether you are using a teledyne Isco Ready sonde or other
SDI-12 compatible sonde, you will need to tell the 6712 if you
want to store all of the parameter data or data from selected
parameters.
Data is stored in memory partitions. A fixed amount of memory
is available to store data. If you are using some parameters to
simply trigger an event or enable condition, it is not necessary to
store the data.
If all of the parameters’ data will fit in memory, you will be asked
if you want to store all of the parameter data. Answering “NO”
will still allow you to selectively store parameter data; otherwise,
all data will be stored.
You will be asked to store parameter data during the setup
process. You can also manually change the setup using options in
the Hardware menu.
To access the setup option in the Hardware menu, select Other
Function from the main menu, then choose Hardware. Advance
through the screens until you see one that displays SDI-12
DATA.

You will be prompted that you have entered a new hardware
setup and asked if you want to erase the stored data. Indicate
“YES” or “NO.” A partition memory status message will be dis-
played and (if a parameter exists that can be calibrated) you will
then advance to the calibration screen (refer to “SONDE CALI-
BRATION AND VALIDATION” on this page). If you do not want
to calibrate or validate, select “DONE” to return to the Hardware
Options screens.
6.6 Sonde Calibration and It is recommended that calibration of your sonde be done
in the lab, according to manufacturer’s recommendations.
Validation
However, for your convenience, the 6712 allows for field cali-
bration of pH, Dissolved Oxygen (DO), and Oxidation Reduction
Potential (ORP).
Field calibrations are stored in the sampler, NOT the sonde, and
are used to modify readings from the sonde until a new sonde is
connected. When a sonde is moved to another sampler, it will
retain calibration constants set in the lab, but will not retain any
that were set in the field.
Although field calibration is limited to three parameters, you can
validate any of the available parameters. Validation allows you
to immerse the sonde in a known solution, note the readings, and
see if the sonde is functioning properly. The validation process

Section 7 Remote Operation
The 6712 controller can be operated remotely from external
devices. External controlling devices may be a computer via
RS-232 serial communications or a telephone via touch-tone com-
mands. Remote telephone operation requires the
factory-installed 2400 baud talking modem.
7.1 Computer Operation
The 6712 controller can be operated from a remote location using
a computer. There are two different levels of computer control.
One level—menu control—is used to start and stop the current
sampler program (or programs if in Extended programming
mode) and to access other menu commands. This level of remote
operation relies on the sampler program for much of its capabil-
ities.
The second level—external program control—relies on external
programmatic control to drive the operation of the sampler. The
external controller can turn on the sampler, take a sample, and
request sampler status data. When under external program
control, the sampler controller program and current operation
state are ignored. The pump, distributor, and serial data output
simply respond to the external commands.
Each level of operation is discussed in the following sections.
However, before using either level of control you must first
establish RS-232 serial communication between the computer
and the 6712 controller. To do so:
1. Connect your computer to the 6712 controller’s interroga-
tor connector with a standard interrogator cable, P/N
60-2544-044 (for 9-pin serial ports).
2. Configure your communications software (HyperTerminal,
for example) for:
·
·
·
·
·
a baud rate no higher than 19,200
no parity
8 data bits
1 stop bit
VT100 terminal emulation.
3. Using your communications software, connect to the sam-
pler. Press “?” on the computer keyboard until the sampler
returns its banner string. A “>” prompt will appear on the
screen when it is ready to accept commands.

Section 7 Remote Operation
7.1.1 Menu Control
Menu commands can be entered from a remote location using a
To access the menu commands, type MENU at the “>” prompt
and press ENTER. The screen will return a list of the available
options. Note that the current state of the controller will
determine the available menu options. Then, type the desired
command(s), confirming with ENTER.
Table 7-1 6712 Remote Menu Commands
Menu Command Description
0 or START
This command will start immediately any program that has been run and is currently waiting to
start.
1 or RUN1
This command will load Program 1 as the sampler’s current Extended program, reset partition if
the storage interval has been changed, and run the program. RUN1 is valid when the sampler
is in standby, or when it is waiting for a start command. RUN1 will also run the current program
while in Standard programming.
2 or RUN2
3 or RUN3
4 or RUN4
These commands will load the selected program number as the sampler’s current Extended
program, reset partition data if the storage interval has changed, and run the program. They are
valid when the sampler is in standby, or when it is waiting for a start command. The commands
are available for Extended programming only.
5 or DISABLE
This command is similar in functionality to a pin F low signal (a signal typically used to enable or
disable the sampler from a flow meter). At run time, the sampler starts with the sampler in the
enabled state. DISABLE is valid while a program is running. If successful, a display of REMOTE
ENABLE IS FALSE will be returned.
A Remote Disable is the highest priority disable. If the sample is disabled with this command,
no condition other than menu command 6, ENABLE, will allow the program to become enabled
again.
6 or ENABLE
This command is used to re-enable a disabled sampler. ENABLE is valid while a program is
running. If successful, a display of REMOTE ENABLE IS TRUE will be returned.
7 or TAKE_SAMPLE This command causes the sampler currently running a program to take a sample. The sample
will count as one of the program’s samples and is placed in the current bottle (Part A’s current
bottle when using two-part programming). TAKE_SAMPLE is valid while the program is run-
ning, after the start time, but not while in the MANUAL PAUSE screens. If successful, a
response similar to PUMPING XXML SAMPLE INTO BOTTLE ## will be returned. If not, a
response similar to NO SAMPLE, PROGRAM WAITING START will be returned.
ST or STATUS
This command causes the sampler to return its status information and current parameter data.
SD or
SCREEN_DUMP
This command causes the sampler to return the information currently displayed on the sam-
pler’s screen. The remote screen follows the sampler’s display as the information is updated.
This mode can be used to observe from a remote location while the sampler is programmed
on-site.
P or PAUSE
This command causes a sampler currently running a program to enter the MANUAL PAUSE
menu. While you are connected in this mode, the sampler keypad becomes disabled, and your
computer’s keypad will be redirected to simulate the sampler keypad. The following keys will be
activated:
<Enter>, decimal point, and number keys.
<Esc>, S, or s = STOP.
<Backspace>, L or l, and U or u = Left/Up arrows.
R or r, and D or d = Right/Down arrows.

Section 7 Remote Operation
Note
You can retrieve the sampling reports at any time using the
same serial connection. Type “Q” to exit the menu. Then at the
> prompt, type “REPORT” and press Enter. The sampler con-
troller will send reports as configured.
7.1.2 External Program
Control
Under external program control, the pump and distributor
operate according to received commands. An external program
can be as simple as manually-entered commands to collect a
sample when needed, or as complex as a user-developed process
control program that directs sample collection according a
system’s needs.
The 6712 controller will respond to four commands:
Turn on the sampler – If the sampler is OFF, the sampler
responds by placing itself in the ON state and returning a status
description of this string.)
The command to turn the sampler ON is:
STS,2
Note that commands and responses are comma-separated pairs.
The first set of alpha-characters are an identifier; the second set
of numeric characters indicate the value. The 6712 controller will
not receive and process the command unless it is followed by a
carriage return.
Checksum optional
Optionally, commands to the sampler can be validated using a
checksum. Checksum validation can avoid problems caused by
faulty program control or communication lines. When using the
checksum, add the CS identifier and a comma at the end of the
command. and the checksum value of the string up to the last
comma. For example, the command with checksum validation to
turn the sampler on would appear as:
STS,2,CS,582
The numeric value of each character is its ASCII equivalent
expressed in decimal format. The checksum of “582” was calcu-
lated as shown below.

6712SR Refrigereated Sampler
Section 7 Remote Operation
Take a Sample – This directs the sampler to take a sample. The
command specifies how much volume to take, and which bottle to
place the sample in. The sampler responds by taking a sample
and returning a status string that reports the new status. A
command to take a sample would appear as:
BTL,2,SVO,100,CS,1039
This example instructs the sampler to place the distributor arm
over bottle 2 (BTL,2) and take a 100 ml sample (SVO,100).
While most settings of the sampler program (start times,
enables, distribution schemes, etc.) are ignored when responding
to external commands, the sampler does rely on two program set-
tings that “configure” the sampler. These settings are:
• Number of Bottles–is used to determine the distributor
arm position and the acceptable range for the BTL
values.
• Suction Line Length–Used with liquid detection to
deliver correct sample volumes according to the SVO
value.
Send Status – When receiving this command, the sampler
returns a data string that identifies the controller and lists its
current status.
The status is received as pairs of comma-separated identifiers
and values. A complete description of each pair is listed below.
MO,6712, is the model number of the sampler.
ID,2424741493, is the sampler’s unique ID number.
TI,35523.50000, is the sampler’s current time.
STS,1, is the sampler’s current status. The possible states
are:
1 = WAITING TO SAMPLE.
4 = POWER FAILED (for short time after power is
restored).
5 = PUMP JAMMED (must be resolved before continu-
ing).
6 = DISTRIBUTOR JAMMED (must be resolved before
continuing).
9 = SAMPLER OFF.
12 = SAMPLE IN PROGRESS.
20 = INVALID COMMAND. Possible causes may be:
· identifier code is not supported.
· bottle requested is not in current configuration
· sample volume requested is outside its range
(10 - 9990 ml)
· day (Set_Time) must be 5 digits and more
recent than 1977
21 = CHECKSUM MISMATCH.
22 = INVALID BOTTLE. (bottle requested is not in the
current configuration)

Section 7 Remote Operation
23 = VOLUME OUT OF RANGE. (the sample volume
requested is outside its range (10-9990 ml)
STI,35523.41875, is the most recent sample time.
BTL,2, is the bottle receiving the most recent sample.
SVO,100, is the most recent sample’s volume.
SOR,0, is the results of attempting the most recent sample.
The possible results are:
· 0 = SAMPLE OK.
· 1 = NO LIQUID FOUND.
· 2 = LIQUID LOST (not enough liquid to satisfy
requirements.)
· 3 = USER STOPPED (using the Stop Key).
· 4 = POWER FAILED.
· 5 = PUMP JAMMED.
· 6 = DISTRIBUTOR JAMMED.
· 8 = PUMP LATCH OPEN.
· 9 = SAMPLER SHUT OFF (while sampling).
· 11 = NO DISTRIBUTOR.
· 12 = SAMPLE IN PROGRESS.
CS,xxxx is the byte-by-byte sum of the entire string
“MO,...,CS,”
Note
For commands that are not understood (INVALID COMMAND
or CHECKSUM MISMATCH) or when no samples have been
taken, the most recent bottle information is left off the response
string.
Send Data – When receiving this command, the sampler
returns the Send Status appended with data from any module,
returned string.

7.2 Telephone Commands 6712 controllers equipped with an internal voice modem can be
operated using telephone commands. This factory-installed
option includes a 12 ft (3.6 m) modem cable.
After connecting to the sampler from a touch-tone telephone,
command numbers may be entered from the telephone’s keypad,
followed by the # (pound) button. The commands are listed in
Table 7-4.
To use telephone commands:
1. Dial the sampler’s telephone number. When the sampler
connects, it answers with “Teledyne Isco Sampler Site
[number].” If the sampler does not receive a touch-tone
command in five seconds, it assumes that a computer
modem has called and initiates the modem connect
sequence. If this occurs you must hang up and try again.
2. Enter the command. For example, to run program 1, press
1
# .

8.1 Maintenance
Checklist
• Clean the condenser coil annually.
• Clean the refrigerator’s air filter every 3 months.
• Clean the refrigerator interior and exterior periodically.
• Inspect the pump tube for wear. Replace it if necessary.
• Clean the pump tubing housing.
• Change the suction line if necessary.
• Clean the bottles, suction line, strainer and pump tube.
• Check the humidity indicator.
• Check the controller’s internal battery status and
replace the battery every five years.
• If the keypad label has bubbles under it, the air inside
the controller has expanded. To release this pressure,
unscrew the flow meter cable or cap on the back of the
controller. Push down on the label to force the air out,
then re-tighten the cable connector or cap.
8.2 Cleaning Guidelines
8.2.1 Refrigerator
To keep the refrigerator’s exterior and interior free from cor-
rosive solutions, grease, oil, and other debris, clean it periodically
with soapy water using a sponge or nonmetallic brush. Do not
direct a hose spray toward the underside or into the front grille.
Wipe the refrigerator dry after cleaning. Apply a coat of fiber-
glass wax to the exterior surfaces to make them easier to clean
and to protect them from damage.
8.2.2 Controller
When necessary, clean the controller with warm soapy water. To
prevent moisture damage, always cap the connectors at the back
of the controller tightly. Keep the controller power cable con-
nected, or replace the protective cap (shipped with the sampler)
over the power source connector.

Make sure the two pump drain holes (located on the bottom
right-hand side of the pump, beneath the pump band) are open
and free of debris or buildup.
8.2.3 Sample Bottles
The sample bottles have a wide mouth to facilitate cleaning.
Wash them with a brush and soapy water, or use a dishwasher.
You can autoclave the glass bottles.
8.2.4 Suction Line, Pump
Tube, and Discharge
Tube
Clean the suction line, pump tube, and discharge tube by placing
the end of the suction line in a cleaning solution and pumping it
through the delivery system. Rinse with clean water. If these
items are severely contaminated, discard them. For critical sam-
Priority Pollutants.
8.2.5 Strainer
8.2.6 Air Filter
Clean the strainer with a brush and soapy water.
The air filter prevents dust, lint, and other debris from circu-
lating around the cooling system. Clean the filter about every 3
months; more frequently under severe operating conditions.
To remove the filter:
1. Disconnect power from the refrigerator.
2. Remove the screws securing the refrigerator’s grille. (See
Appendix D Replacement Parts.)
3. Remove the grille and filter.
4. Steam clean the filter or wash it in hot, soapy water. After
washing, treat the filter with a standard filter coat.
8.2.7 Condenser
Clean the condenser and surrounding areas annually; more fre-
quently under severe operating conditions.
1. Disconnect power from the refrigerator.
2. Remove refrigerator’s back panel. (See Appendix D,
Replacement Parts).
3. Vacuum the fan, compressor, and surrounding areas.
4. Check the fan for freedom of movement. If the fan and fan
motor do not rotate freely, replace the motor. (You cannot
oil the sealed fan motor bearings.)
5. Remove the front grille and filter. Vacuum the condenser
coil and surrounding areas.
6. Clean the filter before replacing it.
7. Replace the back panel and front grille.
8.3 Cleaning Protocols for Clean sampling equipment is essential for valid laboratory
analysis. Teledyne Isco recommends that you develop cleaning
Priority Pollutants
protocols in consultation with a laboratory analyst when
designing the monitoring program. For example, to clean sample
bottles, suction line, and pump tubes, Lair (1974) suggests these
protocols used by USEPA Region IV Surveillance and Analysis
field personnel engaged in NPDES compliance monitoring. The

8.4.2 Pump Tube Alarm
The sampler tracks the pump counts in both the forward and
reverse cycles with a resettable counter. When the counter
reaches the default count of 1,000,000 or the count you have
entered, the sampler displays a message, “WARNING!
REPLACE PUMP TUBE.” The message appears each time you
turn the sampler on or run a program until you reset the counter.
After replacing the pump tube (see page 8-8), reset the count to
zero so the sampler can begin tallying the pump counts for the
new tube. Replacing the pump tube does not reset the counter.
Experience may suggest a significantly different pump tube life.
You can change the alarm count to represent the pump tube life
for your application. The example below shows how to set the
alarm count and reset the pump counts.

8.4.4 Diagnostics
The sampler has several self-diagnostic tests that check the
memory (both the RAM and ROM), pump, and the distributor
arm position. It also contains screens that let you reset the
sampler’s program settings and memory to factory settings.
You do not need to run the diagnostic tests on a routine basis.
The diagnostic tests are a troubleshooting tool; Teledyne Isco’s
Customer Service department staff may ask you to run these
tests when they work with you in diagnosing problems with your
sampler.
Access the diagnostic screens by selecting Other Functions from
the main menu, then Maintenance, and Diagnostics. The unit
will automatically test the memory and display; you can choose
whether it tests the pump and distributor, and whether it reini-
tializes the unit to its original factory settings.

Pump Test – Screen 4 lets you start the pump test by selecting
YES. As the sampler runs the test, it first runs the pump forward
for a short period. Next, it displays an ON/OFF ratio number.
After displaying the forward pumping ratio, the sampler reverses
the pump to obtain a purge ratio. The acceptable range is
between 0.80 and 1.25. If either ratio is outside the acceptable
range, the pump requires repair. You do not need to pump liquid
while running the test, and you can run the test with or without
a tube in the pump.

Section 8 Maintenance
CAUTION
Tests indicate that the pump produces sound levels in excess
of 85db at one meter. Prolonged exposure to this sound level
could result in hearing loss and requires the use of protective
ear plugs.
Distributor Test – The distributor test is provided for factory
personnel to verify the distributor’s position as it rotates through
the 24 positions. (screens 9 through 11). The distributor arm
flexes slightly when it contacts the stop, and the sampler mea-
sures this flexure. The sampler uses this measurement to
position the arm accurately over each bottle.
Reinitialize Controller – The sampler allows you to reset all
the program settings to the settings shipped with the sampler
(screen 12). Reinitializing also clears the memory that stores the
sampler’s event log and module data. Use this option cau-
tiously.
8.5 Replacing the Pump
Tube
Replace the pump tube only with Teledyne Isco’s 6712 pump
tubing. Other pump tubes will not work. The 6712 pump
tubing is easily recognized by the blue alignment collars.
Improper pump tubes include those made for Teledyne Isco’s
other samplers (3700, GLS, etc.) and tubing from non-Teledyne
Isco vendors. Also note that the discharge tube is not the same as
the pump tube. You could experience several problems if you
install the wrong pump tubing:
• The sampler will not pump the liquid.
• Pump jams
• Inaccurate sample volumes
• Faulty liquid detection
Inspect the pump tube periodically. Replace the tube when it
cracks or appears worn. Inspect the tube frequently when the
sample liquid contains a high percentage of suspended or
abrasive solids.
Checklist For Replacing Pump Tube:
1. Disconnect power from the sampler.
2. Loosen the liquid detector’s cover by unscrewing the black
knob on top of the detector. Unlatch the pump band. (The
band is the rounded metal band that holds the tube in the
pump.)
3. Pull the tube away from the bulkhead fitting. Pull it from
the pump and detector.
4. Clean the pump rollers and the inside of the pump band.
5. Thread the new tubing through the pump so that the tube
follows its natural curve around the pump rollers. You may
need to move the pump rollers to make the installation
easier.
8-8

6712SR Refrigerated Sampler
Section 8 Maintenance
6. The blue collars on the tube help align the tube in the
detector and pump. Align the tube by placing the collars in
the grooves inside the liquid detector.
7. Close the detector’s cover and tighten the black knob. Close
the pump strap and latch it.
9. Take a “dry” grab sample to test the tube installation.
WARNING
The pump’s safety lock prevents the sampler from running
the pump when the pump band is open. DO NOT tamper
with the safety mechanism. The pump is extremely
powerful. The pump rollers can injure you severely if the
sampler activates the pump while you are working on it or
inside it. Disconnect power from the sampler before
replacing the pump tube.
Note
To extend the pump-tube life:
• Always use Teledyne Isco pump tubes.
• Install the tube properly, aligning the blue collars correctly in
the liquid detector’s grooves.
• Follow the natural curve of the tube when wrapping the tube
around the pump rollers.
• Minimize the line rinses and sampling retries in the sampling
programs
• Use the shortest possible suction line.
Conditions that shorten tube life:
• Improper installation.
• Abrasive materials suspended in sample liquid.
• Frequent line rinses.
• Long purge cycles, such as those used with long suction
lines.

8.6 Opening the
Controller Case
You will need to open the controller case to gain access to:
• The desiccant bag that dries the controller’s interior
• The battery that provides backup power to the controller
CAUTION
The circuit boards can be damaged from a discharge of static
electricity. Always use an antistatic mat when opening the con-
troller to protect the circuit boards.
To open the case:
1. Pull the discharge tube and pump tube away from the
bulkhead fitting.
2. Remove the distributor arm by unscrewing the nut that
attaches the arm to the distributor shaft. DO NOT
ROTATE THE DISTRIBUTOR ARM MANUALLY;
THIS WILL SEVERELY DAMAGE THE DISTRIBU-
TOR DRIVE GEARS.
3. Remove the controller from the refrigerator.
4. Open the case by removing the 11 screws that attach the
case bottom to the case top.
Note
The case top and bottom fit together with a sealed
tongue-and-groove joint. Any damage — nicks or cuts — to
the tongue, groove, or sealing gasket prevent the case from
sealing completely when you close it. Use extreme care when
opening the case to avoid damaging the joining surfaces.
access to the main circuit board and battery, remove the two dis-
tributor connectors and the EMI shield.
8.7 Replacing the
Desiccant
A humidity indicator, labeled “INTERNAL CASE HUMIDITY,” is
located to the right of the keypad. It indicates the amount of
moisture present inside the control box. The paper indicator is
blue when the control box is dry.
The control box is a completely sealed unit. You do not need to
open the control box during normal operation. The 6712 Sam-
plers use a desiccant bag inside the controller case to prevent
moisture damage to its electronic components. Thus, the
humidity indicator should remain blue under normal conditions.
If moisture does accumulate, the numbered areas on the indi-
cator will turn light pink or white, starting with the area num-
bered “20.” This indicates that the relative humidity inside the
8-11

6712SR Refrigerated Sampler
Section 8 Maintenance
control box exceeds 20%. As more moisture accumulates, the
areas numbered “30” and “40” will turn light pink or white, indi-
cating relative humidities of 30% and 40% respectively.
If the 30% area of the humidity indicator turns light pink or
white, open the control unit, inspect it for leaks, and replace the
desiccant bag.
CAUTION
Do not attempt to reactivate the used desiccant. Reactivation
may cause desiccant to leak out of the bag, causing mechani-
cal damage inside the controller.
Follow the instructions in Opening the Controller Case in Section
box (part #69-9003-518) at the front of the case and replace it
with a fresh bag of desiccant (part #099-0002-00).

8.8 Replacing the Internal
Battery
A lithium battery housed inside the controller maintains power
to the sampler’s memory when the controller is disconnected
from a power source. If it discharges completely, the sampler will
lose all program settings and all data stored in memory when the
external power source is disconnected. The battery requires
replacement every five years. The sampler keeps track of the
time that has passed since the battery was installed. To view this
information, select INTERNAL BATTERY form the Maintenance
screen (see example at left). After five seconds, the sampler asks
if you have replaced the internal battery (see example at left).

8.9 Error Messages
If the sampler detects an error that prevents it from taking a
sample or continuing the program, it displays an error message.
OPERATION ERROR:
PUMP JAMMED
There are messages for the following conditions:
• PUMP JAMMED
• NO LIQUID DETECTED
• NO MORE LIQUID
• PUMP LATCH OPEN
• SAMPLER SHUT OFF
• BOTTLE FULL
• DISTRIBUTOR JAMMED
• PROBABLE OVERFLOW
• POWER FAILED
• LOW BATTERY
• USER STOPPED
• SAMPLE IN PROGRESS
• NO DISTRIBUTOR ARM
Since the sampler may encounter more than one error during a
program, it does not display the messages continuously. Instead,
it records each error and the time it occurred in the Sampling
Results and Combined Results report. It alerts you to the
recorded errors by displaying the message, “ERRORS HAVE
OCCURRED DURING PROGRAM.”
Error Messages
ERRORS HAVE OCCURED
DURING PROGRAM
If the sampler detects a low battery condition, it stops the
running program and displays the “LOW BATTERY” error
message. A low battery condition exists when five consecutive
sample events have resulted in a POWER FAILED error
message.
FATAL ERROR

6712SR Refrigerated Sampler
Appendix C General Safety Procedures
The safety of the personnel who use the 671SR is a critical con-
sideration. The following procedures, applicable to working in
and around manholes and sewers, are those used by Black &
Veatch, a respected consulting firm, and are published here by
their permission.
Field personnel must keep safety uppermost in their minds at all
times. When working above ground, rules of common sense and
safety prevail. However, when entering manholes, strict safety
procedures must be observed. Failure to do so could jeopardize
not only your own life, but also the lives of other crew members.
WARNING
The 6712 samplers have not been approved for use in
hazardous locations as defined by the National Electrical
Code.
CAUTION
Before you install any sampler, you must take the proper
safety precautions. The following discussion of safety proce-
dures offers only general guidelines. Each situation in which
you install a sampler varies. You must take into account the
individual circumstances of each installation.
Additional safety considerations, other than those discussed
here, may be required. Check applicable guidelines, codes, and
regulations of federal, state, city, and county agencies.
C.1 Hazards
There are many hazards connected with entering manholes.
Some of the most common hazards are:
C.1.1 Adverse Atmosphere
The manhole may contain flammable or poisonous gases or the
atmosphere may be deficient in oxygen. Forced ventilation may
be necessary.
C.1.2 Deteriorated Rungs
C.1.3 Traffic
Manhole steps may be corroded and not strong enough to support
a man. It may be difficult to inspect the rungs because of poor
lighting.
Whenever manholes are located in the traveled way, barricades
and warning devices are essential to direct traffic away from an
open manhole.

6712SR Refrigerated Sampler
Appendix C General Safety Procedures
C.1.4 Falling Objects
Items placed near the manhole opening may fall and injure a
worker in the manhole. All loose items should be kept away from
the manhole opening. This applies to hand tools as well as
stones, gravel and other objects.
C.1.5 Sharp Edges
C.1.6 Lifting Injuries
C.2 Planning
Sharp edges of items in or near a manhole may cause cuts or
bruises.
Unless proper tools are used to remove manhole covers, back
injuries or injuries to hands or feet may result.
Advance planning should include arrangements for test
equipment, tools, ventilating equipment, protective clothing,
traffic warning devices, ladders, safety harness, and adequate
number of personnel. Hasty actions may result in serious injuries.
Time spent in the manhole should be kept to a minimum.
C.3 Adverse Atmospheres
[Refer to the table of Hazardous Gases at the end of this
appendix.] Before workers enter a manhole, tests should be made
for explosive atmosphere, presence of hydrogen sulfide, and
oxygen deficiency. Combustible or toxic vapors may be heavier
3
than air, so the tests on the atmosphere must be run at least /4 of
the way down the manhole.
Whenever adverse atmosphere is encountered, forced ventilation
must be used to create safe conditions. After the ventilating
equipment has been operated for a few minutes, the atmosphere
in the manhole should be retested before anyone enters the
manhole.
When explosive conditions are encountered, the ventilating
blower should be placed upwind to prevent igniting any gas that
is emerging from the opening. When a gasoline engine blower is
used, it must be located so that exhaust fumes cannot enter the
manhole.
If testing equipment is not available, the manhole should be
assumed to contain an unsafe atmosphere and forced ventilation
must be provided. It should never be assumed that a manhole is
safe just because there is no odor or the manhole has been
entered previously.
C.4 Entering Manholes
Since the top of the manhole is usually flush with the sur-
rounding surface, there may not be anything for the person who
is entering the manhole to grab on to steady himself. Persons
who are entering manholes should not be permitted to carry any-
thing in their hands as they enter the manhole, to ensure that
their hands will be free to hold on or grab if they slip. A good
method for entering a manhole is to sit on the surface facing the
manhole steps or ladder, with the feet in the hole and the arms
straddling the opening for support. As the body slides forward
and downward, the feet can engage a rung, and the back can rest
against the opposite side of the opening. If there is any doubt
about the soundness of the manhole steps, a portable ladder
should be used.

6712SR Refrigerated Sampler
Appendix C General Safety Procedures
A person should never enter a manhole unless he is wearing per-
sonal safety equipment, including a safety harness and a hard
hat. Two persons should be stationed at the surface continuously
while anyone is working inside a manhole, to lift him out if he is
overcome or injured. One man cannot lift an unconscious man
out of a manhole.
The persons stationed at the surface should also function as
guards to keep people and vehicles away from the manhole
opening. To avoid a serious injury, a person should not be lifted
out of manhole by his arm unless it is a dire emergency.
“When more than one person must enter a manhole, the first
person should reach the bottom and step off the ladder before the
next one starts down. When two men climb at the same time, the
upper one can cause the lower one to fall by slipping or stepping
on his fingers.
C.4.1 Traffic Protection
In addition to traffic cones, markers, warning signs, and barri-
cades, a vehicle or a heavy piece of equipment should be placed
between the working area and oncoming traffic. Flashing
warning signals should be used to alert drivers and pedestrians.
Orange safety vests should be worn by personnel stationed at the
surface when the manhole is located in a vehicular traffic area.
C.4.2 Removing the Covers
Manhole covers should be removed with a properly designed
hook. Use of a pick ax, screwdriver, or small pry bar may result
in injury. A suitable tool can be made from 3/4-inch round or hex
stock. Two inches of one end should be bent at a right angle and
the other end should be formed into a D-handle wide enough to
accommodate both hands. Even with this tool, care must be exer-

2-inch projection should be inserted into one of the holes in the
cover, the handle grasped with both hands, and the cover lifted
by straightening the legs which have been slightly bent at the
knees.
C.4.3 Other Precautions
Other precautions which should be taken when entering a
manhole are:
• Wear a hard hat.
• Wear coveralls or removable outer garment that can be readily
removed when the work is completed.
• Wear boots or nonsparking safety shoes.
• Wear rubberized or waterproof gloves.
• Wear a safety harness with a stout rope attached.
• Do not smoke.
• Avoid touching yourself above the collar until you have
cleaned your hands.
C.4.4 Emergencies
Every member of the crew should be instructed on procedures to
be followed in cases of an emergency. It is the duty of each crew
chief to have a list of emergency phone numbers, including the
nearest hospital and ambulance service, police precinct, fire
station, and rescue or general emergency number.

C.4.6 Lethal Atmospheres in
Sewers
The following is an article written by Dr. Richard D. Pomeroy,
and published in the October 1980 issue of “Deeds & Data” of the
WPCF. Dr. Pomeroy is particularly well known for his studies,
over a period of nearly 50 years, in the field of the control of
hydrogen sulfide and other odors in sewers and treatment plants.
He has personally worked in a great many functioning sewers. In
the earlier years he did so, he admits, with little knowledge of
the grave hazards to which he exposed himself.
“It is gratifying that the subject of hazards to people working in
sewers is receiving much more attention than in past years, and
good safety procedures are prescribed in various publications on
this subject. It is essential that people know and use correct pro-
cedures.
“It is less important to know just what the hazardous compo-
nents of sewer atmospheres are, as safety precautions should in
general be broadly applicable, but there should be a reasonable
understanding of this subject. It is disturbing to see statements
in print that do not reflect true conditions.
“One of the most common errors is the assumption that people
have died from a lack of oxygen. The human body is able to
function very well with substantially reduced oxygen concentra-
tions. No one worries about going to Santa Fe, New Mexico, (elev.
2,100 meters), where the partial pressure of oxygen is equal to
16.2% (a normal atmosphere is about 21%) oxygen. “When first
going there, a person may experience a little ‘shortness of breath’
following exercise.
“People in good health are not afraid to drive over the high
passes in the Rocky Mountains. At Loveland Pass, oxygen
pressure is 13.2% of a normal atmosphere. At the top of Mt.
Whitney, oxygen is equal to 12.2%t. Many hikers go there, and to
higher peaks as well. After adequate acclimation, they may climb
to the top of Mt. Everest, where oxygen is equal to only 6.7%.
“The lowest oxygen concentrations that I have observed in a
sewer atmosphere was 13 percent. It was in a sealed chamber,
near sea level, upstream from an inverted siphon on a metro-
politan trunk. A man would be foolish to enter the chamber.
Without ventilation, he might die, but not from lack of oxygen.
“It seems unlikely that anyone has ever died in a sewer from suf-
focation, that is, a lack of oxygen. Deaths have often been
attributed to asphyxiation.’ This is a word which, according to
the dictionary, is used to mean death from an atmosphere that
C-4

6712SR Refrigerated Sampler
Appendix C General Safety Procedures
does not support life. The word has sometimes been misinter-
preted as meaning suffocation, which is only one kind of asphyxi-
ation.
“In nearly all cases of death in sewers, the real killer is hydrogen
sulfide. It is important that this fact be recognized. Many cities
diligently test for explosive gases, which is very important, and
they may measure the oxygen concentration which usually is
unimportant, but they rarely measure H2S. Death has occurred
where it is unlikely that there was any measurable reduction in
the oxygen concentration. Waste water containing 2 mg per liter
of dissolved sulfide, and at a pH of 7.0, can produce, in a chamber
with high turbulence, a concentration of 300 PPM H2S, in the
air. This is considered to be a lethal concentration. Many people
have died from H2S, not only in sewers and industries, but also
from swamps and from hot springs. In one resort area, at least
five persons died from H2S poisoning before the people were
ready to admit that H2S is not a therapeutic agent. Hardly a
year passes in the US. without a sewer fatality from H2S as well
as deaths elsewhere in the world.
“The presence of H2S in a sewer atmosphere is easily deter-
mined. A bellows-and-ampoule type of tester is very satisfactory
for the purpose, even though it is only crudely quantitative.
When using a tester of this type, do not bring the air to the
ampoule by way of a tube, as this may change the H2S concen-
tration. Hang the ampoule in the air to be tested, with a suction
tube to the bulb or bellows.
“Lead acetate paper is very useful as a qualitative indicator. It
cannot be used to estimate the amount of sulfide, but it will
quickly turn black in an atmosphere containing only a tenth of a
lethal concentration.
“Electrodes or other similar electrical indicating devices for H2S
in air have been marketed. Some of them are known to be unre-
liable, and we know of none that have proved dependable. Do not
use one unless you check it at frequent intervals against air con-
taining known H2S concentrations. A supposed safety device
that is unreliable is worse than none at all.
“Remember that the nose fails, too, when it comes to sensing
dangerous concentrations of H S.
2
“Various other toxic gases have been mentioned in some publica-
tions. It is unlikely that any person has been asphyxiated in a
sewer by any of those other gases, except possibly chlorine. The
vapor of gasoline and other hydrocarbons is sometimes present in
amounts that could cause discomfort and illness, but under that
condition, the explosion hazard would be far more serious. The
explosimeter tests, as well as the sense of smell, would warn of
the danger. Pipelines in chemical plants might contain any
number of harmful vapors. They, too, are sensed by smell and
explosimeter tests if they get into the public sewer. Such occur-
rences are rare.
“The attempt to instill a sense of urgency about real hazards is
diluted if a man is told to give attention to a long list of things
that in fact are irrelevant.

Appendix C General Safety Procedures
“Be very careful to avoid high H2S concentrations, flammable
atmospheres, and hazards of physical injuries. Remember that
much H2S may be released by the stirring up of sludge in the
bottom of a structure. Obey your senses in respect to irritating
gases, such as chlorine (unconsciousness comes suddenly from
breathing too much). Be cautious about strange odors. Do not
determine percent oxygen in the air. There is a danger that the
result will influence a man's thinking about the seriousness of
the real hazards. Most important, use ample ventilation, and do
not enter a potentially hazardous structure except in a good
safety harness with two men at the top who can lift you out.”
