Compass offset (angle of magnetic variation/declination)
Because the angle of variation varies with respect to the geographic position, the
NS360
must be adjusted according to the specific location to achieve the
maximum accuracy and synchronization between the GPS unit and the magnetic
compass. The angle of variation is the actual angle observed between the true
North geographic position and the actual North magnetic position.
To compensate for the magnetic variation, you need to adjust the parameter
COF
(Compass Offset) as follows :
•
Switch off your
NS360
.
•
Press
and the upper screen
simultaneously. ’SET’ is displayed on
the upper line of the display.
•
COF (Compass Offset) is displayed on the mode line of the lower screen
•
Use the arrows
to enter the required variation corrective value The
first digit will display ’W’ or ’E’ for a west or a east variation, and the
remaining 2 digits are the actual angle, adjustable from 0 to 45 degrees.
•
Press
to store the value, BOF (Boat Offset) is now displayed.
•
Go through all the parameters to exit the SET mode or press and hold
for
more than 4 seconds until the device turns off.
