High precision electrical measurement

Basic measurement: total active/reactive/apparent electricity measurement, active/reactive/apparent electricity measurement of each phase (apparent only for communication reading);

Fine measurement: positive and negative total active/reactive energy, four quadrant reactive energy (all only for communication reading);

Data retention: It can record electrical measurement records for 12 transfer cycles, only for communication reading.

Flexible time-division multiple rate billing

Parameter configuration: Supports up to 4 rates, 12 time periods, 8 daily time period tables, 12 annual time zones, 90 public holidays, and can set weekly holiday time period tables;
