Aux Analog Input Setup - Calibration

 

Overview

 

The auxiliary analog inputs can be calibrated using the touch screen and a calibrator.  Before performing this procedure on a newly installed controller, the unit needs to be powered on for at least thirty (30) minutes for a warm up period to allow the inputs/outputs to stabilize with the environment.

Each auxiliary analog input has a zero and span calibration value. A cold junction trim value must be calibrated for thermocouple inputs.  The cold junction trim value must be performed, if necessary, after the zero and span calibration.
