Whole Range - Covers all sample readings which have been logged.
Cursor Range - Covers all sample readings between two cursors.
1. Click and drag the yellow indicator on the button display in the left
part of Diagram I enables equally divide all sample readings into
4 divisions (up to 130). This can also be done by clicking on
or by keying in the figure directly.
/
Note: You might not be able to see this diagram, this is an
example to show you the graph that select whole range
to 40 and cursor range to 40 .
2. As shown in the middle top of Diagram I-1, by changing the cursor
position, you will find an example for the statistic screen of
temperature records .
1021 samples located at the temperature of 44oC( or 213 samples
at the temperature of 62.7o between two cursors' range as shown
C
in the middle bottom).
3. If you set all sample readings into 100 divisions, you will find the
histogram of whole range changed as well.
4. Diagram I-2 is another example of setting the cursor range; it has
been set into 100 division as well.
5. If you compare Diagram I, I-1,I-2, you will notice the differences
of changing setting have also changed the related figures.
6. For the model OM8829 ( Temperature & Humidity datalogger ) , you
will see Diagram J-1 as an example, the upper diagram shows the
cursor 1 temperature , the lower diagram shows the Relative
Humidity records. Diagram J-2 set division as 130.

Maximum :
The greatest value of whole logged records, or
the greatest value between two selected cursors , or
the greatest value of whole Humidity records.
Minimum : The least value from the logged records , or
the least value between two selected cursors, or
the least value whole logged Humidity records.
(Model: OM8829)
Mean
: Average value from the logged records , or
average value between two selected cursors , or
average value from whole logged Humidity records.
(Model: OM8829).
Std. Dev. : This is a very useful feature to see more reliable
deviation while recording . Calculate each deviation
between each value and Mean value, then get an
average figure from totalism deviation.

F.A.Q.(Frequently Ask Question)
FAQ: If I can't down load and the display won't active, what
should I do ?
Ans: Make sure you have selected correct baud rate , see page
select 4800 baud rate for model OM8800D , or select 9600 baud
rate for the rest models. This is to ensure you could download
quicker by selecting correct baud rate value .
FAQ: If the logger is not flashing , how should I do ?
Ans: If you were set up Magnet start function , when a magnet
passes over the middle of rear side , the logger is not flashing
, change with a new and stronger magnetism and try it again.
Make sure the flashing interval is the same as programmed
sampling time . If you were set 5 minutes as sample rate , the
LED will just flash every 5 minutes .
