Deviation Table
The magnetic heading may be affected by permanent magnetic parts of steel, lines with
direct current flow or magnetic soft iron parts in that manner, that the heading information
deviates. With correction values (deviation values) the deviation fault can be corrected.
This correction value is entered via the operation unit to the distribution unit and is used to
correct the magnetic heading information.
The deviation table provides correction values which can be set, changed or erased.
Variation and deviation are used to determine the True Magnetic
Heading and must be checked and updated by the user.
