Error-Air Temperature Sensor Is Not Connected Using the Laser Tracker

If you are receiving an "Air Temperature Sensor is Not Connected" error message when running the trackers Startup Checks, then you should verify that you have an air temperature sensor connected to the trackers Master Control Unit (MCU).

 

If you have an air temperature sensor connected to the trackers then either the air temperature sensor or the MCU is not operating correctly and the air temperature will need to be entered in manually to resume measurements immediately. This can be done using the following steps:

 

1. Connect to the tracker using FARO Utilities.

2. Open up Tracker Pad.

3. Press Set Weather Configuration…

4. Change Air Temperature from Hardware to Manual.

5. Enter an accurate air temperature for the environment that the laser beam is travelling through. If this air temperature is not accurate, the radial distance measurement between the tracker and the SMR will be off 1 part per million for every 1°C error.

6. Press Apply.

7. Press OK to return to the Tracker Pad.

8. Press Initialize. After the tracker has initialized, close the Tracker Pad.

9. Close the FARO Utilities.

NOTE: When using these steps to overcome the air temperature sensor not being read correctly, you may need to compensate the tracker more often in the early stages of measurement because the Warm-Up phase of the tracker was not able to be performed. If you are working in an area that has frequent temperature changes, you should periodically update the air temperature to maintain accuracy.

When the tracker is turned off and turned back on, this setting will revert back to Hardware.

 

You will need to contact FARO Customer Support at for guidance on getting either the MCU repaired and / or the Air Temperature Sensor replaced to resolve the issue permanently.
