Calibration Procedures

Linearisation of the Wind Sensor and
Instrument
Each wind direction sensor has slightly different
electrical characteristics. To provide a highly
accurate display of wind direction data these
characteristics must be entered into the wind
display. This process is called linearisation.

Alignment of the Wind Vane and Display

It is very difficult to align the mast head
transducer in an exact fore and aft position during
installation on the mast. The NAVMAN W100
allows the user to carry out adjustments to the
displayed wind direction after the transducer is
installed.

Wind Speed Calibration

The NAVMAN W100 wind speed transducer is
factory calibrated to read the correct wind speed
under normal conditions. If necessary the user
is able to make adjustments to the wind speed
reading.
Note:
When first installing the NAVMAN W100, the
Linearisation should be performed first,
followed by Alignment then Wind Speed.

Linearisation

Whilst in Alignment mode, press the
keys until the display shows LE. The display will
flash for 6 seconds before displaying LE.
Rotate the wind vane through two complete
revolutions to allow the NAVMAN W100 to
perform the automatic linearisation process. The
vane can be rotated in either direction.
