11.4 Returning Unit
If the unit has to be returned, it should be carefully packed in the original packaging and
returned to your authorised Gill distributor, with a full description of the fault condition.
11.5 Status
The Status code is sent as part of each wind measurement message.

12 TESTS
12.1 Bench test
1.
Couple the WindSonic to the host system and power supply, using a known working
test cable.
2.
Check that the unit is correctly configured by going into Configuration mode and using
D3
See Section 10.6 Checking the configuration.
3.
Check for normal output data, and that the Status Code is OK – 00 (or A for NMEA
format).
4.
If the status code is other than 00 or A, refer to Section 11.5 Status (error) codes.
5.
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.
6.
Note that this is a quick functional test. There are no calibration adjustments; the unit is
designed NOT to require re-calibration within its lifetime.

12.2 Self-Test (Still Air)
This test checks Alignment and Checksums.
Alignment tests:
The unit performs a transducer geometry check and compares the result
with its factory setting.
Checksum tests:
The unit performs a check of its program and data memory.
Important. This test is a stringent laboratory test, which will only be passed if carried out
under still air conditions at room temperature (17-23
˚C).
1.
Use the original packing box (inner and outer) to enclose the unit. (The packaging is
designed as a zero wind enclosure).
2.
Go into Configuration Mode * ENTER .
3.
Carry out the Self-test by entering D 6 ENTER .
A message similar to that shown below will be generated:
ALIGNMENT LIMITS:0D59,0CF5
ALIGNMENT U:OD15 *PASS*
ALIGNMENT V:OD16 *PASS*
CHECKSUM ROM:AB7D AB7D *PASS*
CHECKSUM FAC:04F4 04F4 *PASS*
CHECKSUM ENG:082A 082A *PASS*
CHECKSUM CAL:A9C1 A9C1 *PASS*
For each of the Alignment tests a Pass or Refer to Manual message is generated.
For each of the Checksum tests a Pass or Fail message is generated.
4.
If any of the tests fail, contact your supplier.
If a “refer to manual” message appears please
see Section 11.3 Fault Finding.
Note that it will only pass if the specified temperature and zero wind conditions are met.
Check that there are no visible obstructions or damage to the unit before contacting Gill or
your authorised distributor for further advice.
12.3 Calibration
A Custom calibration is available from Gill Instruments. This must be specified at the time
of order or the unit must be returned to Gill Instruments for retrospective calibration.
