2. Function overview:
1. Time-sharing measure reactive power, forward and reverse rates and maximum demand and time for each active and reactive power, measure active and reactive total power.
2. It can program 4 kinds of rates (tip, peak, flat, and valley), 8 day time period, 12 periods of time, and 4 time zones.
3. Except positive active power accumulation, reverse active power records reverse total, tip, peak, flat, valley electricity and recent 10 reverse operation starting time.
4.The external clock chip has the function of calendar, timing, anniversary switching automatically and temperature compensation.
5. LCD display with a wide viewing angle. Parameters display in turn automatically and the buttons display clearly.
6.With a RS485 interface and an infrared communication interface, and PC or PDA can communicate with the meter through the two communication interfaces, and both sides can communicate at the same time without interference.
7.Active,reactive testing pulse output, 1Hz clock output, multi-functional output and alarm lights alarm
8. It can record loss of voltage, phase failure, lose of current, overvoltage, under voltage, over current, voltage qualification rate, blackout and electricity recover, programming, demand reset and broadcasting timing ,etc.
9.It has functions of button, infrared and optical wake-up when blackout occurs. Optical wake-up is optional (within 3 days blackout), and it can wake up infrared meter reading.
9. It has the functions of fault information prompt, alarm (LCD, alarm lights, buzzer).
10. Load curve record
11. Instant freeze, zero freeze, forward active power freeze when time zone goes to end.
Load representative days the whole point of active power record.
12. Optional open the cover record.
13. Data saving period of validity after blackout: ≥10 years
14. LCD display all information, electricity quantity display 6 bits interger,1 bit decimal.
