If you are receiving the error "Air Temperature Sensor is Not Connected" when running the tracker's Startup Checks, then you should verify that you have an air temperature sensor connected to the tracker's Master Control Unit (MCU).
If you have an air temperature sensor connected, 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:
- Connect to the tracker using FARO® Utilities.
- Open Tracker Pad.
- Click Set Weather Configuration…
- Change Air Temperature from Hardware to Manual.
- Enter an accurate air temperature for the environment that the laser beam is traveling through. If this air temperature is not accurate, the radial distance measurement between the tracker and the Spherically Mounted Retroreflector (SMR) will be off 1 part per million for every 1°C error.
- Click Apply.
- Click OK to return to the Tracker Pad.
- Click Initialize. After the tracker has initialized, close the Tracker Pad.
- Close FARO Utilities.
NOTE: When using these steps, 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 completed. 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 for guidance on getting either the MCU repaired and / or the Air Temperature Sensor replaced to resolve the issue permanently.
