Can measure active energy and reactive energy respectivety

2 . Multi-tariff function

a. Four tariffs,ten time intervals
b. Calendar for acentury(1996-2095) can switch automatically
c. Record and store the total active energy and reactive energy and active energy and reactive energy under kinds of tarifs

3 . Demand statistics

a. Record active max demand and its occurring time
b. Demand statistics adopts slip method
c. Max demand is stored as per month
d. Automatically alarm and trip for overload

4 . Record voltage loss
a. Record 9 voltage loss and information of power failure,also,can record their initial and restoring time.
b. Record total active energy and reactive energy of no voltage loss phase

5 . Programming and meter reading
a. Rs485 communication interface
b. The programming and meter reading are performed by RS485 communication interface , infrared communication interface and plam computer,also it can perform meter reading through remote controller and alternation disaying.

6 . Meter reading at zero o' clock

a. The setting day for meter reading 1st-28th of every month, the meter can calculate and store the data in the last month at zero oclock of setting day
b. Can store and display calculated data for past three months at the same time

7 . Meter reading at power off

The meter is provided with individual meter reading batteries,so it can finish meter reading at power off
