Hello,
I am using NI 9211 Thermocouple module to measure the temperature in a Temperature Chamber (TC). TC has a inbuilt temperatute indicator.
For temp.< 40°C thermocouple (K type) shows good reading with approx. 1°C accuracy. But at higher temperatures there is a big difference approx. 5°C
between the values from Thermocouple and Temperature Chamber indicator.
attached pic shows the thermocouple config.
Can anyone tell me the reason, why the behavior is like this?
