MAGNETIC PROPERTIES MEASURING METHOD AND MAGNETIC PROPERTIES MEASURING DEVICE

摘要

Even in the event of a change of lift-off amount of local magnetic properties of the steel distribution reliably and with the purpose of measuring, the magnetic characteristics measuring method, a lift-off relationship between the amount of the output device of the potato and potato sex sex element in the all cases of the subject for pre-measurement (L _S (l)) and the case all lift-off step of acquiring in advance as data, the output device of the potato and potato sex sex element in the defect portion of the subject for pre-measurement of the amount of lift-off relationship (L _P (l)) and a defect portion lift-off step of acquiring in advance as data, the output of the potato castle element according to the test (x) and the output (x) of the lift is obtained when the device of the potato castle and a measuring step of measuring the OFF (l), all of the lift-off gun data, the defect portion lift-off data, and by using the lift-off amount measured in the measuring step, of the potato in the subject measured in the measurement step and a correction step of correcting the output operation (x) of the element. ;
