Balancing the Horizontal ring
After the Sensitive element has been replaced, the Gyro compass should
be turned ON as described on page 13.
When 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 /-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 level.
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!
