3.1 Configuring and Connecting the Analog Inputs
The analog signals are connected via front connector X3. There are 16 differential inputs
available with protection against overvoltage.
The input sensitivity of the analog inputs can be selected with jumpers:
0 to 51.2 mV for thermal e.m.f. (as supplied)
0 to 512 mV for general voltage input values
All the analog inputs are affected.
