NI-9211 + Type K Thermocouple

[KoBe]

Hi people,

I have some questions on the NI-9211. I didn't find any description in the documentation of NI-9211, how the cold junction temperature is measured (IC or Resistive, Voltage or Current Reference). The point is that I would like to make a cold junction compensation by the use of the "Convert Thermocouple Reading.vi".

Additionally I want to use the Autozero value. How do I have to use this value? Just subtract/add to the raw voltage of each thermocouple? Does the Autozero must be applied also to CJC voltage to assure best results or only for TC0..3 channels?

Thanks

Here is some info on the CJC in a 9211

I believe if you are using the scan engine then the autozero and CJC are done for you automatically.
