PURPOSE:To more precisely monitor the supply voltage of a device to be monitored by compensating the voltage drop, etc., of wiring between the devices in respect of a voltage monitor system to monitor the supply voltage of the device to be monitored at a monitoring device side. CONSTITUTION:A monitoring device 1 monitors the supply voltage of the device 3 to be monitored on the basis of monitoring voltage sent from the device 3 to be monitored. The reference voltage output part 32 of the device 3 to be monitored outputs analog voltage to be reference voltage. Besides, a voltage converting part 31 converts the output level of the supply voltage of the device 3 to be monitored side into the analog voltage, and outputs it to the monitoring device 1 side. When a voltage regulation informing switch 33 is turned on, the device 3 to be monitored side outputs the reference voltage from the reference voltage output part 32 in response to this on-signal, and sends it to the monitoring device 1, and the monitoring device 1 side of the other side considers the sent voltage to be the reference voltage, and generates a voltage conversion table. The monitoring device 1 monitors the supply voltage of the device 3 to be monitored by this voltage conversion table. |
