Thermocouple readings not accurate SCXI 1122-1322

[Goostophe]

Hi, I have an issue with reading thermocouple temperatures using my SCXI-1122 module and 1322 thermocouple block (K-type thermocouples). I am also using a laptop to run LabView and a DAQ-6062E card to communicate. I have fiddled with the Measurement & Automation set-up to communicate with my LabView program and I believe that this is the root of my problem. I have run the program on other computers and NI lab-stations and it has worked, but it is not working with this particular computer or mobile labstation. Hopefuly this is an accurate description of my issue.

Had a look at the DAQ express vi that performs your temperature acquisition

It would help us answer better if you could describe: How much variations are you observing in the measured to the actual temperature?
