I'm looking for the specifications for the thermistor in an SCXI-1303 so I can purchase some new ones.
I have a SCXI-1303 module where the CJC reading went bad and after some troubleshooting, I determined it was the CJC circuit. The thermistor is reading about 2ohms at room temperature and the manual says it should be approx. 5Kohms.
The specifications for the SCXI-1303 are shown on page 11 of the SCXI-1303 32-Channel Isothermal Terminal Block Installation Guide and Specifications. However, I believe in order to verify that the temperature sensor is still within specifications, we should perform a proper calibration. I recommend following the steps outlined in the SCXI-1303 Terminal Block Calibration Procedure. It is possible that the sensor may have fallen out of calibration and if this is the case, I recommend you send in the unit for repair.
