Adjust Internal Cold Junction Temperature

Use the Fluke 9101-256 or a lag bath to calibrate the internal cold junction

temperature.

Use the Fluke 9101-256

To use the Fluke 9101-256 to calibrate the internal cold junction temperature:

1. Connect the Fluke 9101-256 and the 714B via the J type thermocouple

sensor, as shown in Figure 17.
