Claims (1)
定電流電源の電圧に相当する基準電圧とを比較し
、定電流が崩れた状態で繰り返しパルス信号を発
するコンパレータ回路と、ＣＲの時定数を調節し
、コンパレータ回路から受けるパルス信号が継続
する間は１パルスになるように信号を発するモノ
ステーブルマルチバイブレータとを備えることを
特徴とする交流抵抗計の定電流電源監視装置。 A comparator circuit that compares the voltage across the resistor to be measured with a reference voltage corresponding to the voltage of the constant current power supply just before the constant current collapses, and repeatedly issues a pulse signal when the constant current collapses, and adjusts the time constant of the CR. and a monostable multivibrator that emits a signal so that the pulse signal received from the comparator circuit is one pulse while the pulse signal continues.
