Hello!
I have a NI 9213 that is reading type K thermocouples. The system hasn't been used in at least four years, and the Ni 9213 hasn't been calibrated in over ten years. The CJC in the block is reading as -81.7 C, and my TCs in room temperature are reading -91 C. Could this be due to damage or wear in the NI 9213, or lack of calibration?
Thank you
