Hi!
With the 6210 it is not possible to use signal conditioning. Of course NI has lots of hardware to solve your problem.
I guess the best is, to search in our homepage. Here is a link for portable Signal Conditioning. There you can finde all informations you need:

If you just want to measure a temperature with a thermoelement, you can just use your hardware. With the DAQmx-driver you have the possiblity to choose the cold junction compensation according to your system.
