Magnetic Variation
Allows manual entry of local magnetic variation. A value between
W90 degrees and E90 degrees.
Heading Format
The system can be configured to show heading information in
either MAG (Magnetic) or TRU (True) format. Magnetic Variation
must be set to enable True display format (see section above). A
True Heading is indicated by the TRUE icon in the upper pane;
the absence of this icon indicates a Magnetic heading.
Magnetic Deviation
However carefully the Compass Transducer is positioned, there
is always the possibility of errors being introduced by the vessel
and equipment. To remove errors it is necessary to "Swing" the
compass by turning the boat slowly until the system can optimize
the readings. Once the correction has been completed the
deviation correction value will be displayed (See page 17 for the
calibration process).
On entry, the top pane shows the maximum deviation applied (dashes if
the compass has not been swung).
