．Precise measure three phase active＆reactive energy

．Good linearity, broad dynamic operation range

．Adopting carrier communication module, setting meter number by carrier

．High accuracy, anti-high frequency＆interfe-rence pulse ,etc feature

．Prepaid function＆power-off function when use- rs are in default of money

．Adopting resistance sampling ,which solves completely the leakage energy

of even harmonic in current circuit.

．Very good electromagnetism compatibility

．Infrared meter reading function
