Three-phase current, the voltmeter is used to measure the three-phase AC current, voltage intelligent power distribution
instrument. It uses the international advanced instrument-specific single-chip, combined with the exchange of
sampling, software, automatic lock-like technology, with digital display, variable ratio settings, automatic tuning
and remote communication and other functions, so that power users can more effectively monitor the electricity,
improve energy Level.
