Abstract
PURPOSE: To charge the earth capacity of a measuring line, etc. rapidly and shorten a measuring time by a method wherein a relay contact formed in parallel with a high resistor is attached to a comparator and worked when measuring currents flowing in by the voltage drop of the high resistor.
CONSTITUTION: A set value S1 which instructs applying voltage by numerical value is converted by means of a D-A converter DAC, and currents are supplied to an electronic part DUT through an amplifier AMP, a high resistor RM and a measuring line l1. On the other hand, a comparator COMP is connected to a sensing line l2 applying feedback to the amplifier AMP, and a relay contact Ry1 and a measuring portion ADC connected in parallel with the high resistor RM are worked by the output. Thus, since voltage is applied without passing through the high resistor RM first and earth capacity Cl, Cd is rapidly charged and the voltage drop of the high resistor RM is measured by the operation of the comparator COMP, minute currents such as leakage currents can be measured for an extremely short time.
