Precise measurement on forward and reverse power in active and reactive four-quadrant reactive and max. Demand.precise measurement on each phase voltage, current, active and reactive watt.4 tariff-rate to be set per date and 12season-cost rate ranges per year,4 sets of tariff rate for flexible and adaptive use.Launching automatically by the designated date and store the dateof last and last tow month.Meanwhile, max. demand of current month resets to zero either automatically and manually.1-2day in a week to be set as work-off and converted in to specific tariffrate as required.Records to be kept and to display values in terms of voltage loss, power off. Parameters, battery life and the state of parameters inuse.Infrared remote programming, reading and non-accessible datainterchange.
