Main and Subsidiary Tariff SettingThere are two tariff settings can be programmed in the meter, current active tariff is main tariff and the subsidiary tariff is backup tariff. The switch time for these two settings can be programmed. And there are different symbles on LCD to indicate the main and subsidiary tariff, for main and for subsidiary. When meter is running under season tariff, the two symbols will not displayed.3.8. The record of event3.8.1. OutageMeter can record last 10 times of outage time, starting time, times and accumulative total outage time. 3.8.2. Loss PhaseWhen the power is on at 3 phases 4 wires mode, if the voltage of 1 phase is lower than ug and the casting time is longer than tu, and the current of the phase is lower than 0.5%IB0.05%IB,the phase is Power down; When the voltage of Loss-phase goes higher to ug and casting longer than td, the phase resumes. In 3P3W mode, if the total voltage of element A & C lower than 1.2 times of Un, B phase lose phase. If the voltage of element A&C uauc|u0, and casting longer than tu, and the current of the element lower than 0.5%Ib0.05%Ib, A phase lose phase. When |uauc| is lower than u0, and the casting time longer than td, the phase resume. When loss phase is taking place, happening time, loss phase times and total time will be recorded. Event light will be turned on automatically. After loss phase, ending time will be recorded and alarm will be cancelled. ug: Limited Value for loss phase, can be set up(25VUn，Un=57V or 100V), default 30V.tu: Loss phase casting time, can be set up(1 min99 min), default 1 minute.td: Loss phase resume casting time, can be set up(1 min99 min),default 1 minute.3.8.3. Loss voltageIf the voltage of a loss voltage is lower than 78Un2V, the current is higher than 0.5%Ib+0.05%Ib, and cast longer than te, this phase loss voltage. Loss voltage start/end time, meantime power and total time will be recorded, event light turn on. But, when 3P3W, if voltage of element A&C is lower than Uw, it is not loss voltage.When voltage of the phase resumes to 85%Un2V, and cast longer than tf，timing stops, Loss voltage stops. The meter will record the ending time, meantime power and cancel the alarm.The meter has the function to record all loss voltage events from first time to 10th time, loss voltage times and total times.
