5.3 Set average of channels
The main menu is shown again. Select "Set
average of channels" to adjust the time
settings for the wind parameters and the
analogue output
Select number "3" from the menu shown.
The new window shows what can be set,
The wind speed display part has 3 different
average times, 2 are fixed times and set for 2
and 10 minutes.
The third one is called "users" which means
that the user can set an average time by him
self.
This is done with the menu shown on the
right. The first 3 are for the wind direction, the
average wind direction and the average wind
speed.
The numbers "4" and "5" are the average
times used for the analogue output signals.
Number "6" has to do with the gust display
reset time. If this average time is set to zero the gust display has to be reset manually. Otherwise it
will be reset when the set time here has elapsed.
