1.General       PZ96L-AV3 3 phase voltmeter is a kind of programmable electrical digital meter. It can measure 3 phase voltages accurately. With 4 keys on the front panel, we can set the parameters, such as PT ratio, parameters of commnucation etc..        It can transmit the measure data to analog output or RS485 communication. With digial input or digital output, we can realize alarming or controlling other equipment (contactor) remotely.
