WHAT IS THE PURPOSE OF USER CALIBRATION?

The basic calibration of the controller is highly stable and set for life. User calibration allows you to offset the ‘permanent’ factory calibration to either:

1.Calibrate the controller to the your reference standards.

2.Match the calibration of the controller to that of a particular transducer or sensor input.

3.Calibrate the controller to suit the characteristics of a particular installation.

4.Remove long term drift in the factory set calibration.

User calibration works by introducing a single point, or two-point, offset onto the factory set calibration.
