1586-2586 CJC Module Accuracy Verification
1. Connect the calibrated E-type thermocouples to channel 10 on the Product
(UUT).
2. Insert the thermocouples into a drywell calibrator which is set and stabilized
at 25
°
C.
3. Configure the channels of the Product for an E-thermocouple.
4. Insert the reference thermistor probe into the drywell to measure the actual
temperature.
5. Use the reference thermometer with the reference thermistor probe and the
thermocouples with the Product to measure the drywell temperature until all
readings are stable.
6. Compare the thermocouple readings and reference thermometer reading.
7. The difference should be <0.6
°
C.
