Calibration Offset
Calibration offset allows a device to compensate for an inaccurate sensor, lead resistance or
other factors that affect the input value. A positive offset increases the input value, and a
negative offset decreases the input value.
The input 1 offset value can be viewed or changed with Calibration Offset 1 [CAL1] (Limit
Menu).
