The meter is designed for measurement and metering of active and reactive (or only active) energy of direct and reverse (or only direct) directions, measurement of active and reactive electric power, measurement of network parameters: RMS values of voltage and AC current strength (phase current and neutral current), network frequency, power factor cos, reactive power factor tg, as well as measurement of electric power quality indicators in accordance with class "S": negative and positive deviations of voltage and reactive power (phase current and neutral current). Communication interfaces: Opto-port, RS-485, RF, GSM.
