Proper installation and maintenance of a marine magnetic compass：
Installation: The compass should be installed in a location that minimizes the effects of magnetic interference from the vessel's steel structure and electronic equipment. The compass should be mounted level, and the compass card should be free to rotate smoothly. The compass should also be protected from direct sunlight and extreme temperatures.
Calibration: Once the compass is installed, it should be calibrated to ensure that it is aligned with magnetic north. This involves measuring the deviation at different headings and adjusting the compass to compensate for the deviation. A deviation table should be created to record the deviation at different headings, and compensating magnets or weights should be added to the compass bowl to correct for the deviation.
Maintenance: Regular maintenance is essential to ensure that the compass remains in good condition and continues to provide accurate readings. The compass should be checked regularly to ensure that it is level and that the compass card rotates smoothly. The glass face of the compass should be cleaned with a soft, lint-free cloth to remove any dirt or dust. The compass should also be protected from moisture and extreme temperatures.
Inspection: The compass should be inspected regularly to ensure that it is free from damage and that all parts are in good working condition. The compass bowl should be checked for cracks or other damage, and the compensating magnets or weights should be inspected for signs of wear or damage.
By following these steps, a marine magnetic compass can be properly installed and maintained to provide accurate and reliable readings for navigation. Regular calibration and maintenance are essential to ensure that the compass remains in good working condition and is always ready for use when needed.
