  • Page 53: Test Probe Calibration

    Chapter 10 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 reaching the set-point temperature. After completing operation of the calibrator, al- low the well to cool by setting the temperature to 150°C or less for one-half hour before switching the power off.

  • Page 54: Stabilization And Accuracy

    9150 User's Guide 10.2.1 Stabilization and Accuracy The stabilization time of the calibrator depends on the conditions and temperatures involved. Typically the test well is stable to 0.5°C within 20 minutes of reaching the set-point temperature as indicated by the display. Ultimate stability is achieved 10 to 20 minutes after reaching the set temperature.

  • Page 55: Calibration Procedure

    Chapter 11 Calibration Procedure At times the user may want to calibrate the unit to improve the temperature set- point accuracy. Calibration is done by adjusting the controller probe calibration constants CE1, CE2, and CE3 so that the temperature of the unit as measured with a standard thermocouple agrees more closely with the set-point.
  • Page 56 9150 User's Guide 4. Retrieve the original calibration errors from the unit or the Report of Calibration. 5. Record the previous values for CE1, CE2, and CE3 and calculate new values for CE1, CE2, and CE3 using the following formula.
  • Page 57 Chapter 12 Maintenance • The calibration instrument has been designed with the utmost care. Ease of operation and simplicity of maintenance have been a central theme in the product development. Therefore, with proper care the instrument should require very little maintenance. Avoid operating the instrument in an oily, wet, dirty, or dusty environment.
