WIND 3150 Installation and Operation Manual
NAVMAN
6 Display maximum wind speed
To display maximum wind speed, press until the
maximum speed is displayed, for example:
The maximum wind speed is the highest measured
apparent wind speed since the maximum wind speed
was reset or the unit was switched on.
6-1 Reset maximum wind speed
Resetting starts calculating a new maximum:
1 Press until MAX speed is displayed.
2 Hold + for two seconds.
7 Display VMG (velocity made good)
To display VMG, press until VMG is displayed, for
example see right:
VMG (velocity made good), is the component of boat
speed parallel to the wind. VMG is only available if
the WIND 3150 is connected to a boat speed
instrument.
Note: VMG is always shown in knots.
8 Calibrate wind angle and speed
8-1 Calibrate wind angle
Calibrate wind angle after installation if the masthead
arm is not parallel to the centre line of the boat. If the
displayed wind angle seems inaccurate, first check
that the vane on the masthead unit is not damaged
or corroded, then calibrate wind angle. To calibrate
wind angle:
1 You must know what the correct apparent wind
angle is. The easiest way for a boat with a
motor is to travel at maximum speed when
there is no wind. The correct wind angle is then
from ahead, 0°.
2 Press + several times until the Calibrate
Wind Angle screen is displayed:
3 After two seconds, the LCD display changes to
display the apparent wind angle:
Pointer

4 Press or to change the displayed
apparent wind angle to the correct value.
5 Press .
8-2 Calibrate wind speed
The unit is factory calibrated and should not normally
need calibrating. If the displayed wind speed seems
inaccurate, first check that the rotor on the masthead
unit is not damaged or corroded, then calibrate wind
speed:
1 You must know what the correct wind speed is.
