トテスタ。[Claims for Utility Model Registration] (1) A power supply connected via ground to one end of the parallel circuit for capacitors connected in parallel to the object to be measured, and a power supply voltage to be applied to the parallel circuit. an applied voltage regulator that adjusts the applied voltage, an operational amplifier that applies the applied voltage directly to the other end of the parallel circuit via non-inverting and inverting input terminals, and an operational amplifier that is interposed between the output terminal of the operational amplifier and the other end of the parallel circuit. Discharge consists of a discharge current detection resistor, a voltmeter that measures the voltage across the detection resistor, and a voltage comparator that compares the measured voltage with a threshold voltage that ends the discharge of the capacitor and outputs a discharge termination signal. power circuit. (2) A power supply circuit for both measurement and discharge, in which an ammeter that outputs a steady current value detection signal is interposed between one end of the parallel circuit described in paragraph 1 and the ground. (3) An in-circuit tester comprising the discharge power supply circuit described in paragraph 1 or the measurement/discharge power supply circuit described in paragraph 2.
