Figure 35. Thermocouple CJC Calibration Connections
The calibration of the TC CJC (Cold Junction Compensation) is a critical part of the
calibration process, it is important that the thermocouple junction be allowed to
completely stabilize. Usually this takes a minimum of five minutes.
After the proper connections have been made, type “12” then press the Enter key on the
PC keyboard. Use a lag bath to source a stable temperature the 726. Enter the value of the
temperature and the main calibration menu will reappear. The temperature scale used is
ITS-90.
