| Abstract: | For continuously geomagnetic observation,correct judgment should be made to working states of a instrument through analyzing and calculating observed data.In this paper,two methods to judge if the electrical current in bias coil of a FHD Instrument is inverse and some methods to make correction,based on the variation of baseline value before and after the inverse,are introduced. |
