■With KW8M Eco-POWER METER, electrical power (voltage, current, etc.), power factor, frequency,
etc are measured using AC voltage and AC current input via one of the following systems:
single-phase two-wire system, single-phase three-wire system, three-phase three-wire system or

can it be legally used for billing.
