It is used to measure and display the direct reading of voltage and current values in the electrical line. The meter can be used as a general digital voltmeter/ammeter and can be installed with the analog output module to make it a voltage or current transmitter with the function of displaying the primary circuit measurement value. You can also choose the relay output module to add the voltage and current limit alarm protection function. And can also select multiple functional modules at the same time to make it with the functions of measurement, alarm, transmission, and communication.
