Wrong reading from 9213

Hi all

I have a NI-9213 connected with a cDAQ-9171 and a J type thermocouple.

I am testing the unit and measuring the room temperature. In LabVIEW it shows about 23 degrees celsius, and in other room temp measurment devices it shows about 26 degrees (which I tend to think is the more accurate room temp).

Does anyone knows why?

Does it have to do with calibration?

Is it not meant to measure room temp?

Any kind of help would be greatly appreciated.

Thanks in advance,

Vlad.
