10. Once the calibration has completed, a pop-up will appear with the message Calibrate Complete. Click OK to
acknowledge and the results will then be displayed on the screen in the Results column (see Figure 7.30).
Calibration will fail if the stability cannot be achieved or the sensor offset is greater than 0.3°C (0.5°F).
The validity of a sensor can be checked by hand warming the sensors to see if there are changes in the
readings on the DataLINE screen. If calibration will not complete, replace and recalibrate the sensors.
Refer to the Sensor Replacement procedure.

11. After completing the calibration event, download a DCX file and check that all of the following information is
captured: service center name, location, the results of the calibration and the offset applied. Ensure that all
the information is captured and the event is considered a success when all the intended sensors in
calibration have passed.
NOTE
If there is “uncal” in the download, it means that the calibration process was not completed.
12. After the completion of the calibration, restore the unit to its original state.
7.29.4 Sensor Replacement
Always turn OFF the unit circuit breaker (CB-1) and disconnect main power supply before
removing electrical parts.
1. Place the Start-Stop switch (ST) to “0” to turn the unit Off. Disconnect the power supply.
NOTE
Include white date code label when cutting out and removing defective sensors. The label could be
required for warranty returns.
2. Cut the cable. Slide the cap and grommet off the bulb type sensor and save for reuse. Do not cut the
grommet.
3. Cut one wire of existing cable 40 mm (1-1/2 inches) shorter than the other wire.
4. Cut the replacement sensor wires (opposite colors) back 40 mm (1-1/2 inches). See Figure 7.31.
