Analog Inputs
Offset adjust / Span adjust
Manually fine-tune the offset adjust and span adjust values to
remove process errors. These are calculated values applied
to the raw input signal.
Note.
If simulating thermocouple inputs, connect the
millivolt source using appropriate compensating cable – see
Section 5.4.2. For 2-lead resistance thermometers, either
connect the resistance box at the sensor end of the leads or
add the lead resistance to the calibration values.
