Thermocouple
Cables
Calibrated Thermocouple Cables with recorded correction values shall be used
throughout this procedure to adhere to the expanded instrument uncertainties provided
in Appendix B. Thermocouple Cables must be calibrated to the accuracies listed in the
Thermocouple Calibrator Specification column of Appendix A, or better.
Thermocouple Cables are only required for each desired thermocouple type.
The thermocouple cables must be terminated at one end with a male miniature
thermocouple connector for connection to the UUT. The opposite end should be
terminated as appropriate for the thermocouple calibrator.
For two channel UUTs, a split or “Y” cable may be used, terminated with two (2) male
miniature thermocouple connectors. Correction values must be established for each leg
of the Split Thermocouple Cable.
Copper Mini-
TC Cable
Copper Mini-TC Cable is required for Voltage Gain and Offset alignment only. This cable
does not require calibration.
One end shall be terminated with a male miniature thermocouple connector for
connection to the UUT. The opposite end shall be terminated with copper connections
appropriate for the DC Voltage Source.
For two channel UUTs, a split or “Y” cable may be used, terminated with two (2)
male miniature thermocouple copper connectors.
Straightened
Paper Clip
Required to access the calibration enable switch. Any rigid wire, approximately 0.8
mm in diameter, may be used.
