Calibration of the analogue output
1. Mounting the module
The SG module has to be installed in a cabinet in compliance with (inter)national electrical
regulations. Connection details are printed on the upper face of the amplifier housing.
The amplifier module supports 6 wire technique. If you are using a 4 wire load cell, the
“Exc +” and “Sen +” terminals must be shorted together as well as the “Exc –“ and “Sen –“
terminals.
2. Adjustment settings
All DIP-switches and potentiometers are positioned near the top edge of the housing.
3. Setup DIP-switches
Low pass filter:
By combining the six DIP-switches the low pass filter can be set from 0.25 Hz up to 32 Hz.
Factory default is 32 Hz.

Zero setting:
The six DIP-switches permit the off-set to be coarsely set in steps of 2.5% of 3.2 mV/V over the
range + or – 80%. The 25-turn potentiometer permits trimming to <0.002%.
