2. Electric Power Measurement— Positive active power, reverse active power can be measured, and according to which setting for active group. For active power, it can accumulate and storage total, top, peak, flat, valley power. It can storage and display total power and power for each tariff for last 12 months.
3. Multi Tariff— With 2 sets of tariff, which can changeover automatically on appoint time. Each tariff can support for 4 rates. It can set 14 time zones in a year, and program at most 14 periods in 24 hours. The minimum time interval is 15 minutes for periods, which can be set over 0: 00am.
4. Ladder Billing— With function for ladder billing, two programs of electrovalence, which can be changed over automatically at appoint time or reach appoint electricity consumption.
5. Event Log— With function for logging events such as clear, program, timing, power down, switch out, switch on, open meter cover and etc.
6. Electricity Freezing— With multi freezing ways of instantaneous freezing, timing freezing, day freezing, appoint freezing, on hour freezing and etc.
7. Load Profile— It can profile kinds of operation for query analysis.
8. Measure Function— Real time measuring and displaying current voltage, current (including zero line current), power, power factor and gird frequency, and it can also display the operating parameter such as direction of power.
9. Demand Operating— Handle parameter setting, prepaid electricity charge, information write back, switch out and switch on demand to the meter through solidity or virtual medium.
10. State Indicator— LED indicators for pulse, warn, switch out, and error code would be displayed on LCD, which can help to understand the working state for meter.
11. Safety Certification— The operations on meter have passed strict safety certification such as password or ESAM module (SM1), to promise for the safe transportation of data.
12. Reliable Design— Perfect power source and electromagnetism compatible design, which are suitable to the strong electromagnetism disturbance and big occasion of power source fluctuation.
13. Communication Mode— Infrared+RS485 interface, carrier communication module.
