The calculations for zero and span are now stored and you will see:
Upper Display = The cold junction temperature at the rear terminals
Lower Display = CJTEMP (10004)
The value in the upper display is in tenths of a degree. It is the current reading of the temperature as measured at the thermocouple terminals and recognized by the controller.
You can change this value, if it is in error, using the or
keys.
WARNING: The accuracy of the controller is directly affected by the accuracy of this value. It is recommended that this value not be changed under normal circumstances.
The controller stores the calibration constants and exits the calibration mode.
