Outside Air Temperature Indicator Test

NOTE: To test the outside air temperature sensor.

Troubleshooting:


If the indicator displays ‘‘---'' for more than 2 seconds after selecting the outside air temperature display mode, check for an open in the wire between the gauge and the  outside air temperature sensor.

 

Calibration:


The outside air temperature indicator's displayed temperature can be recalibrated ±3° to meet the customer's expectations.

1.Turn the ignition switch ON (II).

2.Push and hold the trip/reset switch for 10 seconds. While you continue to hold the button, the display will scroll through temperature settings from +3° to -3° as shown.

 


3.When the desired correction value appears on the display, release the buttons, and the recalibrated outside air temperature will be displayed.

If the outside temperature indicator display is off by more than 3 degrees of the desired value, turn the ignition switch OFF and repeat steps 1-3.

NOTE: To recalibrate the display to the true temperature, remove the  outside air temperature sensor (A), but leave it connected. Submerge the sensor and a thermometer (B) in a container of ice water (C). Select the calibration mode as described above, then recalibrate the display to the true temperature.
