3.3.5 Heading Offset (Compass Alignment) H OFF
The Compass Alignment electronically compensates for the
misalignment between the autopilot’s fluxgate compass and the
Earth’s magnetic field.
The boat’s actual heading must be known; use a calibrated bowl
compass or hand-held compass for reference.
Enter the heading offset (in degrees) to correct the misalignment,
in the range -180 to +180. For example: the boats actual heading
is Due North, 000. The autopilot display is indicating West, 270.
Enter the heading offset value of +90. The heading offset should
be checked during a sea trial to ensure that it has been entered
accurately.
3.3.6 Adjusting the Heading Offset
(1) Select H OFF from the menu.
(2) Calculate the correct value for the offset.
(3) Press Enter to store the value.
3.3.7 Magnetic DIP Angle (DIP)
All magnetic compasses are affected by “Northerly turning errors”
in the Northern Hemisphere or “Southerly turning errors” in the
Southern Hemisphere, which increase with Boat Speed and
Magnetic DIP Angle in higher latitudes. These can cause heading
instability at boat speeds greater than 20 knots when steering with
an autopilot. By entering the dip value indicated on the
compensation chart, the autopilot will be able to correct for these
errors and improve the heading stability. Use the minimum value
necessary to stabilise the heading.
Note
This applies to boats faster than 20 Knots only.
3.3.8 Setting the Magnetic DIP Value
(1) Select DIP from the menu.
(2) Select the correct value from the chart below.
