Turn the vessel through a full 360º with the ProPilot 700 in Standby
Mode and note the amount of error at the eight Cardinal and
Intercadinal points.
The compass sensor requires the vessel to turn approximately 2½
times in a CLOCKWISE direction to complete the deviation
correction. Steer your vessel, in a calm sea, to a location well away
from any large iron structures.
With the system powered up in Standby Mode “H035”, press
and hold the ADJ key for three seconds, until “CONF” is
displayed.
Press the ADJ key a further 3 times, the pilot will now display
“CLR” or “COrr” is displayed.
CLr If “COrr” is displayed it means that the autopilot already has
correction values stored. Press the and keys simultaneously
so that previous information is erased and “CLr” is displayed.
“ERR*” is displayed if the compass is located too close to a strong
magnetic field. Move the compass to a more suitable location.
Turn your vessel slowly, in a clockwise direction, aiming to
complete a full turn in 1 to 3 minutes.
INIT Press the and keys simultaneously to start the sequence
running. The ProPilot 700 displays “INIT”.
rUN The display then shows “rUN”.
COrr After 2½ turns the display shows “COrr”, the Auto deviation
correction routine has been completed.
If the compass cannot complete the routine for some reason (it
will continue to display “rUN”) or if you wish to abort the
routine, press the and keys together. The display returns
to “CLr”.
6.2 Align Compass
Having completed the Auto Compass Deviation Correction
procedure you should now check that the compass heading is still
the same as the vessel’s heading, in which case alignment will not
be necessary. If there is a standing error, the compass must be
‘electronically’ aligned with the vessel’s bow.
