The Wind Page
can be used to select:-
North Alignment from
0
-359 degrees.
Sensor WindSpeed
ON
or OFF.
Wind Speed Units
MS,
KTS, MPH, KPH, FPM.
(Metres/Second, Knots (Nautical miles/hour), Miles/Hour, Kilometres/Hour, Feet/Minute).
No-Direction Wind Speed
0.00
m/s to 5.00m/s speed above which direction readings
are output.
Short Term Average
60
(10 -60).
Configures WMO Short Term Average as the defined multiple of the Output rate .i.e. AVGSHORT
10 is a rolling average of the last ten outputs.
Long Term Average
10
(1-10).
Configures WMO Long Term Average as the defined multiple of the short Term Average.
.i.e. if AVGSHORT is 10 then short term average is a rolling average of the last ten outputs.
Then if AVGLONG is set to 10, long term average is a rolling average of the last 100 outputs.
Compass Sensor
ON
or OFF
With Compass Sensor ON Wind Direction readings corrected to magnetic north are output in the
data string (CDIR). If set to OFF then the field with Compass corrected direction reading is left
blank.
WMO Average Wind Reading Notes:
The default output rate from MaxiMet is one new reading every second.
There in this case the WMO averaged Wind reading result will be based on:-
Long Term Average (1-10) x Short Term Average (10-60).
For instance if a
2 minute averaged data
output was required set:-
RWA Long to 2
RWA Short to 60
For these settings then every minute you would get an averaged output reading based on the
previous 2 minutes of wind data.
