Measuring Temperature Using Thermocouples

The Calibrator supports numerous standard thermocouples. See Chapter 7 for
supported thermocouple specifications.
You can use the I 5 key to toggle the cold junction reference location (CJC)
between the internal and external cold junction reference locations. This is used
primarily when you want to use an external cold junction for conducting
temperature measurements. The
the Calibrator is in external CJC mode.
