TERRESTRIAL MAGNETISM COMPENSATOR

摘要

PURPOSE: A terrestrial magnetism compensator capable of performing an N/S compensation by enlarging an N/S compensating amount and compensating a terrestrial magnetism is provided. CONSTITUTION: A terrestrial magnetism compensator comprising: a key input section(50) for inputting a key for a terrestrial magnetism compensator; a DC value output section(40) for outputting a DC value corresponding to the key input; and an adding current output section(60) for adding the N/S compensating current to the DC value of the DC value output section(40) wherein an adding current of the adding current output section(60) is applied to the terrestrial magnetism compensating coil, the adding current of the adding current output section is applied to one terminal of a degauss and an AC voltage is applied to other terminal thereof.
