See Section 83 Checking the configuration.
Check for normal output data, and that the Status Code is OK – 00, 60 or A (for NMEA
format).
If the status code is other than these, refer to Section 9.5 Status (error) codes.
Use an office fan or similar to check that the unit is sensing wind, turning the unit to
simulate changing wind direction and to check that both axes are functioning.
Note that this a quick functional test. There are no calibration adjustments; the unit is
designed NOT to require re-calibration within its lifetime. Gill has provided and Integrity
Check, see next page for details.
