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.
Wind Speed
Press and hold the and keys for 3
seconds.
3 SECS
To increase reading press the key.
To decrease reading press the key.
Each key press results in a 5% change. It may
take 2 or 3 key presses before a change to the
speed can be observed.
To exit press the key.
Alignment
Whilst in Wind Speed mode, momentarily press
the and keys.
AP
Press the and keys to change the
displayed wind direction.
To exit press the key.
Linearisation
Whilst in Alignment mode, press the and
keys until the display shows LE. The display will
flash for 6 seconds before displaying LE.
6 SECS
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.
To exit press the key.
Note:
If there is any doubt about the accuracy
of the display wind direction, repeat the
linearisation & alignment calibration
procedures.
