Definition of “Dip Error”
Dip error refers to the deviation in the readings of instruments caused by the horizontal component of the Earth’s magnetic field. It occurs when the instrument is not perfectly aligned with the Earth’s magnetic field and results in erroneous measurements. This term is closely related to magnetic dip, which is the angle between the magnetic needle and the horizontal plane. Dip error is most significant at high latitudes, where the Earth’s magnetic field is stronger and more inclined. To avoid dip errors, instruments must be properly calibrated and aligned before use.
