%
Note: The value is updated every 0.25 – 10 seconds and transmits the minimum wind quality of
the last measurement.
This value allows the user to assess how well the measurement system is functioning in the
respective ambient conditions. In normal circumstances the value is 90 - 100%. Values up to
50% do not represent a general problem. If the value falls towards zero the measuring system is
reaching its limits.
If during critical ambient conditions the system is no longer able to conduct reliable
measurements, error value 55h (85d) is transmitted for wind speed and wind direction (device
unable to execute valid measurement due to ambient conditions).
