Setting Offset and Gain factor
The analog input modules
and
are equipped with each 4 ADC, the modules
and
with each 8 ADC. The ADC 1 to 4 are on the base PCB
and the ADC 5 to 8 are on an additional PCB which will be plugged into the
base PCB. The input voltage of the ADC is fixed to ±10V.
The potentiometers Ox and Gx are used for an accurate adjustment of gain
and offset (
). The "x" in the potentiometer’s names stands for the num-
ber of the corresponding ADC. The potentiometer names are printed on the
boards.
When testing the modules, the potentiometers have been optimally adjusted.
Therefore we ask you to avoid adjusting the potentiometers if not necessary,
because this may result in inaccuracy. The calibration of the ADC is described
in the
.
