Abstract
A correction winding in which an alternating current flows attributable to magnetic flux generated in an exciting winding when an alternating current is allowed to flow in the exciting winding, is provided for a sensing device. In a state where the characteristics of the sensing device are not changed, electric power is supplied to the exciting winding so that a reference value, which is a digital value of the difference in the potential between the two ends of the correction winding detected by the correction detection circuit, is stored in a RAM of a microcomputer by operating a setting switch, and then divided with a digital value of the difference in the potential between the two ends of the correction winding detected by the correction detection circuit. A value Vso/Vs, which is a result of the division, is used to multiply the digital value of the difference in the potential between the two ends of the detection winding detected by the detection circuit.
