Offset adjust / Span adjust
These are calculated values applied to the raw input signal.
Cannot be adjusted by the user.
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.
