Hi bmlservices,

How are you calibrating your modules? Are you following this document?

actually I was just trying to verify temperatures to within +/- 1 C using labview software. kinda of a quick check thing.

Hi bmlservices,

In that case, you may also need to take into consideration the accuracy and sensitivity of the data acquisition device you are using (i.e. SCXI-1600) and the V/degree C specification for the thermocouple you are using.
