WIND 3150 Installation and Operation Manual
5 Display wind speed
To display wind speed, press
until the speed is
displayed, for example:
If the WIND 3150 is connected to a boat speed
instrument, press
to display TRUE or APP
(apparent) wind angle (see section 3).
4-1 Set wind damping
Wind turbulence, gusts and mast motion cause the
measured wind angle and speed to fluctuate. To give
stable readings, the WIND 3150 calculates wind
angle and speed by measuring the values several
times and averaging the measurements. The wind
damping value ranges from 1 to 5:
A lower value averages measurements over a
shorter period of time. This gives the most
accurate readings but has the most
fluctuations.
A higher value averages measurements over
a longer period of time. This gives the most
stable readings but will ignore some rapid
changes.
Note: Set the damping to the lowest value which
gives stable readings. Values of 1, 2, 3, 4 and 5
average measurements over a time period of 6, 12,
18, 24 and 30 seconds respectively.
