The Calibration and Use of Thermocouple Simulators
Thermocouple simulators and calibrators have greatly simplified thermometer calibration. Their use will be contrasted with historical calibration methods. The paper details the three critical calibration parameters: DC Voltage gain, cold junction calibration, and implementation of the thermocouple curves. The implementation of cold junction compensation internal to the thermometer or thermocouple simulator will be described. An uncertainty analysis will be presented for a specific calibrator based on the guidance of EA-10/11 [1]. And an explanation will be given for reporting measured values of 30,000 degC, much hotter than the surface of the sun, on calibration certificates for the example calibrator.
