ADJUSTMENT OF COMPASS Meaning and
Definition
-
Adjustment of compass refers to the process of aligning a compass to ensure its accuracy and proper functioning. A compass is a navigational instrument that utilizes Earth's magnetic field to determine direction. It consists of a magnetized needle that aligns itself with the Earth's magnetic field, allowing users to find their way.
Over time, external factors such as changes in the magnetic field, exposure to strong magnets, or mechanical wear can affect the accuracy of a compass. Thus, an adjustment is required to realign the compass with the true north. The adjustment is necessary to eliminate any errors in the compass readings and ensure that it points accurately in the desired direction.
The adjustment of a compass typically involves two main steps. First is the adjustment of the declination, which accounts for the difference between true north and magnetic north. This is done by either adjusting the compass dial or by noting the declination value and mentally adjusting readings accordingly. The second step is compensating for any magnetic interference caused by the vessel, equipment, or other objects. This can be accomplished by placing movable magnets or magnetized objects around the compass to counteract the unwanted magnetic fields.
The adjustment of the compass is crucial for navigation, especially when precise direction is required, such as during maritime navigation or land exploration. By ensuring a compass is accurately adjusted, users can navigate efficiently and with confidence, minimizing the risk of errors and misdirection.
