Calibration

In order to provide higher measurement accuracy, the PT1000 measurement can be calibrated. The calibration only calibrates the internal Analog Frontend and not the PT1000 Sensor element itself. The Sensor element must be conform with the standard PT1000 norms.

Tests have shown, that a calibration is most likely not necessary, because the resolution of the 12 bit analog measurement is far worse than the reistance reading error produced by the Analog Frontend. Calibration might only be necessary if no precission reistors in the frontend hardware are used.

Calibration can be performed the following ways:

Command Line Calibration

Use the Command Line Interface to invoke the calibrate command.
