Anschutz Gyro Compass Standard - 20 Service Manual [updated]

Ensure the mounting foundation is perfectly horizontal. Use a machinist’s bubble level on the upper rim of the compass outer container. Adjust the mounting foot-screws until the container sits dead-level.

Holds the supporting liquid, provides the heating and cooling mechanisms to maintain a constant operating temperature, and enables inductive transmission of the heading data.

Verify the heading output on the operator unit matches the main compass reading. B. Quarterly Maintenance
