4.6 Calibration
Note: Install the masthead transducer after the following have been performed. When first
installing the WS150, Linearization should be performed first, followed by Wind Direction
Calibration, then Wind Speed Calibration (if necessary).
4.6.1 Linearization 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 linearization.
1
Connect the masthead directly to the red 5-
pin connector on the WS150.
2
Follow the Calibration Chart until you reach
the Linearization mode. The display will flash
for 6 seconds before displaying LE.
3
To perform the linearization process rotate the
wind vane as many times as necessary for
the wind direction indicator to make a complete
360 degree circle without the indicator stopping
Press & hold for 3 seconds
to enter calibration mode.

4.6.2 Wind Direction Calibration
It is very difficult to align the mast head transducer
in an exact fore and aft position during installation
on the mast. The WS150 allows the user to carry
out adjustments to the displayed wind direction
before the transducer is installed by connecting the
masthead to the red connector on the WS150.
1
Follow the Calibration Chart until you reach
the Wind Direction Calibration mode.
