What is System Error of the Thermocouple?


#1

System error is calculated by adding the accuracy of the temperature sensor (thermocouple) and the accuracy of the meter used to read the voltage signal together.

For example, a Type K thermocouple has an accuracy of +/- 2.2C above 0C. Let’s say the meter has an accuracy of +/- 1C. That means the total system error is +/- 3.3C above 0C.
