ComNav 1500 / 1510 Autopilot - 41 -
6.5.7 C6, Adjust Compass Alignment [ADJ]
Possible settings are [000°] to [359°]. Default setting is [000].
Compass transducer alignment correction or the so called,
”A-fault”.
Allows 180° reversed mounting if needed. Never mount the
transducer at right angles to the boats fore-aft line.
Make sure that the local magnetic variation is entered before
you make the alignment adjustment, otherwise you are unable
to see the difference between local magnetic variation and
alignment error.
To check the transducer position, sail/steer your boat in a straight
line towards two visible objects in a line. If the actual heading taken
from the sea chart is 330° and the compass displays 335°, then set
the value of 360° - 5° to 355°.
