Measuring Temperature Using Thermocouples

The Calibrator supports numerous standard thermocouples. See Chapter 7 for
supported thermocouple specifications.
You can use the   key to toggle the cold junction reference location (CJC)
between the internal and external cold junction reference locations. External cold
junction reference is 0 °C or 32 °F. This is used primarily when you want to use an
external cold junction for conducting temperature measurements. The
message appears on the display when the Calibrator is in external CJC mode.
