Cables
Thermocouple Cables must be calibrated to a 2-Sigma uncertainty of 1 µV or less.
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 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.
