Wind Speed and Direction Averaging
Overview
WMT700 provides average values for wind speed and direction using
either scalar or vector averaging. With both methods, the average is
determined according to the user-configurable averaging time. The
averaging time affects serial communication and analog output similarly.
You can also configure the gust averaging time for calculating wind
extreme values. The default gust averaging interval is 3 seconds, as
recommended by the WMO (World Meteorological Organization).
If scalar averaging has been selected, you can also enable wind direction
coasting to ensure consistent direction measurement results at low wind
speeds.
