Abstract

PURPOSE: To make possible measurement of pulse zener voltage at much larger current in the state of a pulse width of a much shorter time by applying the zener current for measurement of zener voltage in superposition to minute current.
CONSTITUTION: A signal is applied to a control input terminal 9 and the minute current corresponding to zener current b' is applied to a zener diode 3. And the control signal for flowing the required zener current b" is applied to the control input terminal 9 and the zener current b" is flowed for a required time, during which time the zener voltage is measured. Here, there is no need for the voltage drop component owing to load impedance and therefore taking this voltage slightly higher than the zener voltage value of the specimen zener diode 3 suffices and the restriction concerning the dielectric strength of the transistor 4 for switching is reduced correspondingly
