4-4 Calibrate wind speed
The unit is factory calibrated and should not normally
need calibrating, however you should calibrate it if
you believe that the displayed wind speed is
inaccurate:
1
You must know what the correct wind speed is.
The easiest way for a boat with a motor is to
travel at maximum speed when there is no
wind; the correct wind speed is then equal to
the boat speed. Find the boat speed from a
speed instrument in the boat or in another boat
travelling at the same speed.
