Alignment Error Correction 6-13
Performing Alignment Error Correction
1. Determine the existing alignment error by comparing the compass
heading with the vessel's true heading. The true heading must be
known to an accuracy of at least 0.5°.
2. Go to the ”Service Setup 600”
and select the ”HEADING CORR.
(Correction) VALUE” sub menu.

The adjacent SERVICE SETUP
CSU display is shown.
3. Enter the required heading correction value.

The heading correction value equals the alignment error with the
sign reversed.
Example:
The vessel’s true heading is 123.0°,
the compass displays 123.4°,
the alignment error is therefore 0.4°,
thus, the required heading correction value is - 0.4°.
