Setting the Input Voltage Range
The input module Pro-AIn-8/16 Rev. A
voltage range is adjustable by 3jumpers. As a default setting, the ADC is set
to the voltage range of ±10V. The settings for other voltage ranges can be
found in fig. 93.

Fig. 92 – Pro-AIn-8/16 Rev.
After every jumper setting you have to recalibrate the ADC, in order to assure
correct measurement results. The individual steps are described in the
chapter 6 "Calibration".
For the accurate adjustment of offset and gain the potentiometers UO (unipo-
lar) or BO (bipolar) as well as GAIN are available
