· This gauge is a maximum indication gauge that measures zero phase voltages and zero phase currents, memorizes their maximum value, and indicates readings with an analogue needle.
· Even when there happens a power outage during measurement, this gauge can perform measurement for at most 4 hours using its built-in memory.
· When power is re-inputted after a power outage, the previously saved maximum indication value is displayed again.
· This gauge has a self discharging prevention function to protect the built-in battery from being discharged until its installation after being released from the factory.
· This gauge has terminals for reset from the outside on the back.
