6-6 Magnetic Compass Heading Calibration
Deleting entries from the magnetic compass heading calibration table
When a complete new calibration is carried out, it is recommended to
delete old entries from the calibration table first.
Also, if the determined correction values are comparatively small, it is
generally sufficient to enter only a few values for the headings where
the largest deviations occur. By deleting the correction value from a
table entry, the entry is made inactive and the correction applied at the
respective heading is instead calculated by interpolating between the
two adjacent active entries.
To delete entries from the magnetic compass heading calibration table:
1. Call up the User Setup and go to ’Magn
Cal Tab | Enter Values’.
Press ENTER .
The calibration table entry screen is
shown.
2. Delete correction values:
a) With the
Up/Down
arrow keys, select
the entry (’cal. no.’) to be edited.
b) Press
ENTER
to confirm the cal. no.
Press
ENTER
again to move the cursor
down to the ’del. cal.’ line.
c) Press the
Down
arrow key to select
“YES”.
d) Press ENTER to confirm deletion.
e) The cursor returns to the ’cal. no.’
line.
If required, repeat the procedure
from step a above to delete another
value.
3. Press
MENU
to quit the table entry
screen.
