6.8 Balancing the Horizontal ring
After the compass has been running continuously for at least 2 hours, the
Horizontal ring should be adjusted.
1 Locate the reference level tool on the Horizontal ring, and check that
the level bubble is within +/-5 minutes from the center. Each division
equals 2 minutes.
2 If the level bubble is not within this limit, add or remove weights from
the Horizontal ring until it is leveled.
Note!
It is important that there are as few weights as possible on the Horizontal
ring.
3 Let the compass run for at least 20 minutes before the level is
rechecked and eventually confirmed.
WARNING If the Horizontal ring is tilted more than +/-5’, a bearing
error will be generated!
