How can I measure temperature with BNC2110?

[efflorti]

I want to measure temperatures with BNC 2110. Now I have found a BNC adapter which could connect with thermocouples. But I don't know how to add a CJC in the system. Is the instruction below only designed for CJC sensors of NI devices?

Thanks!

I'm pretty sure that the 2110 is not designed to take thermo-couple measurements. You could theoretically do all of the scaling yourself with those scaling VI's, but keep in mind that the wiring will not be properly compensated and that you will have to live with some amount of error.

Thanks! I connect a circuit with analog input, RTD and thermocouple wires. Hopefully I could get the result with Python converting voltage to temperature and adding CJC without too much deviation.
