3) Constant: 1,600imp/k W. h
4) Accuracy: active energy 0.5, 1.0
5) Reactive energy: 1.0, 2.0
6) Operating tempeature: -25 ~ +55o C
7) Power loss: &amp;e;2.0W/phase
8) Starting current: &amp;e;0.004Ib
9) Daily timing error: &amp;e;0.5s/d
10) Battery using life: &amp;e;10 years
11) Period of time error: &amp;e;1min
Functions and features:
1) Function of electric energy measurement
a) Measure positive direction active energy, reactive energy and reversed direction
active energy, reactive energy
b) Record accumulating total energy, last month energy and present energy
c) Time-sharing tariff: total energy, tine energy, peak energy, level energy, off-peak
2) Function of max-demand measurement: can measure max-demand of positive
direction active energy and reversed direction active energy during total, tine, peak,
level, off-peak and vale energy period
3) Function of assistant parameter measurement:
a) Measures A, B, C each phase voltage (1 decimal), A, B, C each phase current (3
b) Electrical net frequency by LCD display
c) Active energy power, reactive energy power (4 decimal), active energy and
reactive energy demand at current one minute
4) Function of incident record:
a) Last month operation/last month power cut time, meter total operation/total
power cut time
b) Meter operation state (loss of phase, loss of current, power direction, current
c) Power cut times and demanding reposition times
d) Current time zone, time period, rate, battery report
e) Finally set the parameter date and time (that is last programmed date and time)
f) Demanding reposition times, finally demanding reposition date and time
5) Function of communication: infrared communication port and RS485 communication
6) By-turns function: can confirm the by-turns parameter by setup
7) Function of program:
a) Marker content: marker number, meter number, parcel number
b) Initialization content: current date, time, program constant, account day, by-
turns content, by-turns display time
c) Time zone setup: can set 4 time zones every year
d) Rest day setup: can choose any 2 days as rest day from Monday to Sunday for
each zone
e) Rate period setup: the rest day has 12 periods in every time zone, and each
period has 4 rate options
f) Working day period rate setup: The rest day has 2 periods for each time zone,
and each period has 4 rate options
g) Whether or not using several rate: using several tariff just has rest day setup
h) Period rate setup: can set 5 period rate beforehand, number 0 is used for rest
day which has 6 periods everyday, each period has 4 rate options. Number 1-4
rates have 12 periods, each period has 4 rate options
