警報するようにした絶縁抵抗計。 A battery power source, a high voltage generation circuit which is supplied with the battery power through a power switch and generates a high voltage of a predetermined value, and a high voltage generated by this high voltage generation circuit is connected to the circuit under test through a pair of measurement terminals. The insulation resistance meter is equipped with a measurement circuit that measures the current flowing through the circuit under test and determines the insulation resistance. A diode and a Zener diode are connected between one end of the measurement terminal and one end of the battery power supply so that when the circuit and the circuit under test are in a live line state, a current due to this live line voltage flows through the output impedance of the high voltage generating circuit. An insulation resistance meter is provided with a current flow path including a current flow path, and when a current flows through the current flow path, the switch element is turned on and an alarm means is driven, thereby giving an alarm that the circuit to be measured is in a live state. .
