Balancing the Horizontal ring
After the Sensitive element has been replaced, the gyro compass
should be started as described on page 10.
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 /-10 minutes from
the center. Each division equals 2 minutes.
2
If the level bubble not is within this limit, add or remove
weights from the horizontal ring until it is level.
Note!
It is important that the total number of weights on the horizontal
ring is as few as possible.
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 +/-
10’, a bearing error may be generated!
