The Anschütz Standard 20 is a north-seeking, free-gyro compass using a liquid-supported, pendulous gyrosphere. Unlike its predecessor (Standard 14), the Standard 20 features an automatic latitude error compensation and a quick alignment mode. Service intervals are critical due to the spinning mass (20,000 RPM) and the conductive liquid suspension.
Check the heating and cooling cycles (to ensure the fluid stays at the correct operating temperature). Inspect the pump motor for noise or vibration. anschutz gyro compass standard 20 service manual
