| Zusammenfassung: | PURPOSE:To reduce variations in the measured value of magnetic characteristics by controlling a voltage applied to an exciting coil to a constant value by a digital meter. CONSTITUTION:The digital meter which controls a voltage in units of 1/100mV is fitted to the terminal part of the exciting coil 2 and a zero voltage is controlled in a constant state. Consequently, variations in measured valued of initial magnetic permeability and maximum magnetic permeability displayed on an X-Y recorder 5 with a pen 6 are reduced through a calibrator 4 to stably measure them. |
