I wrote a Labview program to take temperature measurements using a NI921 plugged into a cDAQ9171. It all worked ok and I did a load of testing. When I came to review the data, I realized I'd incorrectly set some of the channels to j type thermocouples, when I'm actually using k type. Is there a way to convert the temperature data I've captured to valid readings? I'm guessing this will require knowing how the system converted the mV input from the thermocouple to degC for j types, reversing this process mathematically to re-gain the raw mV readings, then knowing how the system converts mV to degC for k types, and applying this.
Can anyone help?

Are you referring to NI-9213 or 9211?
Whichever way it is, you can refer to this link:
Hope this helps.
