Calibration
Introduction
The PRO-PT100 sensor can be calibrated using a 2 point calibration
scheme. At two different known reference temperatures a
measurement is made with the (uncalibrated) PRO-PT100 sensor. The
readings of those temperatures are set in the calibration tool.
The calibration tool will give two parameter values back as return.
Finally these parameter values are set in the PRO-PT100 sensor.
Details
We use two different known temperatures to calibrate the PRO-PT100.
Preferably we choose the temperatures such that they are close to the
outer boundaries of temperatures we expect to measure.
For example you can choose the classic combination of melting ice
water and boiling water as temperature references. The readings of
those temperatures are set in the calibration tool, available in the tem-
perature logger software distribution.
