8.4 Long cables
Communications between the WindSonic1 and the data logger will most likely fail if its cable is
extended beyond 15 m (50 ft). Digital data transfer eliminates offset errors due to cable lengths.
However, digital communications can break down when cables are too long, resulting in either
no response from the sensor or corrupted readings.
9. Maintenance and
troubleshooting
NOTE:
All factory repairs and recalibrations require a returned material authorization (RMA) and
completion of the “Statement of Product Cleanliness and Decontamination” form. Refer to
the
page at the end of this manual for more information.
9.1 Troubleshooting
The WindSonic1 outputs a status code (
(p. 14)) along with each wind direction and
speed measurement. The data logger program can filter out data when the status code is not 00.
If the WindSonic1 is not powered, not connected, is using the wrong COM port, or has missed a
sample, the wind direction and speed measurement will be NaN. The program can filter out
these values and report the number of good samples that were used in computing the online
statistics. If the total number of good samples is less than 98% of the expected samples, send the
WindSonic1 to the factory for repair (see
).
