® ® 1 General 1.1 Introduction Congratulations on your purchase of the Maretron SSC200 Solid State Rate/Gyro Compass. Maretron has designed and built your compass to the highest standards for years of reliable, dependable, and accurate service. The SSC200 detects the direction of the earth’s magnetic field using solid state magnetometers and indicates the vessel heading relative to magnetic north. In addition, the SSC200 incorporates solid state accelerometers and a solid state angul

® ® switched on and off, which makes compensation impractical. Therefore, you should try to mount the compass as far away as possible from these magnetic field sources (doubling the distance between the magnetic field source and the compass will reduce the field strength by a factor of approximately 8). Also, always observe any “compass-safe distance” markings on other electronic equipment. 6. Minimal Vibration – Although the SSC200 is more tolerant of vibration than a fluxgate compass,

The preferred method for deviation calibration is to use a Maretron display (procedure 1) because you receive direct feedback on the calibration process with a clear indication of a successful or unsuccessful deviation calibration. Deviation calibration done automatically at power-up (procedure 2) is less desirable than procedure 1 because it is more d
