3 Wind direction
3-1 Wind direction display
To display wind direction, press
one or more
times, until TRUE (true wind direction) or APP
(apparent wind direction) is displayed. True wind
direction is only displayed if the WIND 3100 is
connected to a speed instrument.
The wind direction is displayed in degrees (0 to 180°
port or starboard) and by the pointer (see right).
3-2 Set wind direction pointer type
The wind direction pointer can be set to one of five
types (see right). Type 1 is the default.
Types 1, 2 and 3 simulate wind vanes, and
have a black spot in the centre. The thinner
part points to where the wind is coming from.
Types 4 and 5 point to where the wind is
coming from.
To set the pointer type:
1
Press
+
several times until the Pointer
Type screen is displayed:
2
Press
or

3-3 Set wind direction damping
Wind turbulence, gusts and mast motion cause the
wind direction to fluctuate. To give a stable reading,
the WIND 3100 calculates the wind direction by
measuring the direction several times and averaging
the measurements. The wind direction damping
value ranges from 1 to 5:
A lower value averages readings over a shorter
period of time. This gives the most accurate
direction but has the most fluctuations.
A higher value averages readings over a longer
period of time. This gives the most stable
direction but will ignore some true changes in
direction.
Note : The damping affects the numeric wind
direction, not the pointer. Set the wind direction
damping to the lowest value which gives a stable
numeric wind direction. Values of 1, 2, 3, 4 and 5
average readings over a time period of 6, 12, 18, 24
and 30 seconds respectively.
