express vi thermocouple reading temperature increase as temp decrease

[1LabViewNewbie1]

Hi there,

I'm using a labiew express vi to take a measurement from a j-type thermocouple. I have, however noticed that a (real) temperature increase is shown as a temperature decrease indicating that I've wired the thermocouple in the opposite way to what labview expects. Is there any way to fix this other than by stripping down my system and redoing my cable?

Cheers,

Aaron

I don't think so.

The CJC math takes into concideration the glavonic potential between the different metals.

So just flip the wires and this will serve as big warining for you some time in the future.
