FIELD: physics. ^ SUBSTANCE: method includes measuring three components of increment of magnetic induction between measuring and compensation sensors, applying longitudinal resistive links between inputs of compensation and measuring channels of each measured components, applying transverse resistive links between output of compensation channel of each measured component and inputs of measuring channels of other components. Bar with measuring and compensation sensors is placed in zone of homogenous magnetic field, components of which are measured by compensation channel. Bar is twice oriented along field of one of coordinate axes of measuring and compensation converters in a way to turn two measured compensates of magnetic induction of field to zero. Increments of magnetic induction between measuring and compensation sensors are measured. Column vector of losses of zeroes of measuring channels is determined. Correction of losses is performed by inserting constant corrections. Bar is thrice oriented along field to turn two measured components of magnetic induction of field to zero, observing vector columns of increments. Components of increments are compensated to zero by finding resistances of correct circuit of transverse resistive link, and appropriate circuit of longitudinal resistive link. ^ EFFECT: lower sensitivity threshold of device. ^ 3 dwg |
