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
[ ] [ ] keys.
NOTE: The accuracy of the controller is directly affected by
the accuracy of this value. Change this value only if the zero
and span calibration procedures did not bring the controller
within the specified accuracy requirements.
The controller stores the calibration constants and exits the

calibration mode.
