Overview

 

 

The series 9120 controller 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.

 

The series 9120 has three analog inputs. Each range 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. There are two analog outputs each with a zero and span value.
