● TOU metering
   the internal clock circuit of energy meter has time automatic switching function.

Calendar, clock and rate can be set and adjustment through RS485, infrared interface.

At least 4 tariffs and 12 time interval can be set within a natural day, min time interval is 15 minutes. Time interval can be set over Zero o’clock.

●   Demand Reading
   Demand Current (per phase present, peak,3 phase)
   Demand Voltage(per phase present, peak)
   Demand active power(3 phase present, peak,)
   Demand reactive power(3 phase present, peak,)
