In many multifunction calibrators used for temperature transmitter calibration, a specific thermocouple is __________.

• A. Simulated
• B. Calibrated
• C. Replaced
• D. Linearized

Answer: (A)

The main idea is that when calibrating temperature transmitters, the device needs to provide a precise, repeatable signal that mimics what a thermocouple would produce at a known temperature. A multifunction calibrator can simulate the output of a specific thermocouple type, giving the correct millivolt signal corresponding to a chosen temperature. This allows you to verify the transmitter’s response and accuracy without using an actual thermocouple at the hot junction, and it supports testing across the intended range. Calibrated would imply the thermocouple itself has been adjusted, which isn’t what the calibrator does. Replaced would suggest swapping the sensor for the calibrator, which isn’t the standard calibration method. Linearized would refer to altering the signal’s relationship to temperature, which isn’t the action the calibrator performs when simulating a thermocouple output.
