IPC: G01R33/16
Filed: 1992-02-20
Abstract: PURPOSE:To avoid the measuring error of the apparatus by a method wherein the output voltage of a differential coil for measurement a specimen for permeability measurement is not inserted is corrected by vectorially subtracting the output voltage when the specimen is inserted, and a permeability is measured from the ratio of the output voltages after the correction. CONSTITUTION:An output voltage from a differential coil 23 for measurement use in an air-core state is stored in an external memory 12 so as to correspond to an oscillation frequency from an oscillator 1. A specimen is inserted into a coil part on one side of the coil 23; a piece of amplitude data and a piece of phase data for the output voltage from the coil 23 and a piece of amplitude data for an output voltage from a coil 24 for magnetic-field detection use are stored so as to correspond to the oscillation frequency from the oscillator 1. When the oscillation frequency from the oscillator 1 reaches a prescribed frequency, the piece of amplitude data and the piece of phase data for the output voltage from the coil 23 in the air-core state are vector- subtracted, under the control of a correction operation means 115, from the piece of amplitude data and the piece of phase data for the output voltage from the coil 23 in a state that the specimen has been inserted. Then, a permeability is found, under the control of a permeability operation and control means 116, from the radio of the output voltage from the coil 23 to that from the coil 24 after its correction.
