9 Test Probe Calibration Calibrating a Single Probe Test Probe Calibration For optimum accuracy and stability, allow the calibrator to warm up for 10 minutes after power-up and then allow adequate stabilization time after reach- ing the set-point temperature. After completing operation of the calibrator, al- low the well to cool by setting the temperature to 25°C for one-half hour before switching the power off.

10 Calibration Procedure Calibration Points Calibration Procedure Sometimes the user may want to calibrate the dry-well to improve the tempera- ture set-point accuracy. Calibration is done by adjusting the controller probe calibration constants R0 , ALPHA, and DELTA so that the temperature of the dry-well as measured with a standard thermometer agrees more closely with the set-point.
