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 a millivolt source using
appropriate compensating cable – see Table 3.1, page 18. For 2-lead
resistance thermometers, either connect a resistance box at the sensor
end of the leads or add the lead resistance to the calibration values.
