SIGNAL INPUT, module ME
OVERVIEW
This module together with the "MP" input board, performs the signal input conditioner
(see Fig. 2). This module contains the trimmers and jumpers for the amplifier gain and
the low level output (offset).
The signal input connections are made at Terminals 3, 4, 5 and 6.
Each signal type use some of these terminals.

The frequency ranges are interpreted as follow : Range A (0 to 40/70 Hz.) which means that the
minimum range is from 0 to 40 Hz, and the maximum range from 0 to 70 Hz. The high level of the
signal output can be adjusted for any value between 40 to 70 Hz.
ADJUSTMENT AND CALIBRATION PROCEDURE
1. When input and output signal values are determined, remove the conditioner case. (Fig.2)
2. Check on the "MA" module, if the selected power supply is correct. (Table 1).
3. Select on the input board the desired Frequency range, according to Table 5, using
jumpers "1", "2", "3", "4", "5" and "6".( Fig. 8).
Set jumpers "7" to "10", for the corresponding signal type (Table 4).
Select on the "MS" output module the desired output (voltage or current), using jumpers
"E" and "F". (Fig. 6).
4. Connect a pulse generator to the conditioner input terminals 5 and 6
5. Connect a digital multimeter to the signal output terminals : 11 and 12 for Voltage output.
: 9 and 10 for Current output.
6. Power up the conditioner with the appropriate power supply.
7. Adjust the pulse generator until it generates the low signal level.
8. Turn the "ZERO" trimmer (P1), located on the "ME" input module, until the multimeter
shows the desired low signal output level. (For example: 0 Vdc).
9. Adjust the pulse generator until it generates the high signal level.
10. Turn the "GAIN" trimmer (P2), located on the "ME" input module, until the multimeter
shows the desired high output level. (For example: 10 Vdc).
11. Repeat steps 7 to 10, until the two values are correct.
