2. Total kWh Register
The total kWh is displayed on the LCD by 6 digits with one decimal.
The total kWh register range is 000000.0-999999.9 kWh.
3. Meter Memory
The history data can store 12 months .
The history data include: Accumulative total and max 4 rates of Wh[abs(Wh+) + abs(Wh-)];
Accumulative total Wh-.
4. Event Record
The energy meter can record below events with time stamp;total 50 events.
Power on.
Power off.
Reset Energy data.
Reset event log.
Reset [energy data+event log].
5. LCD display during power off
Three display modes(can be set):
1. Always display Accumulative Wh[abs(Wh+)+abs(Wh-)].
2. Displaying Accumulative energy for setting time then no display.
3. No Display.
Default LCD display during power off is Mode 1.
6. Maxim Demand
1. Record T1 active (abs(Wh+) + abs(Wh-)）maxim demand ，T2 active maxim demand，T3active maxim
demand，T4 active maxim demand，and the time of the corresponding maxim demand.
2. Use the slip mode, demand cycle / slip time <=15 min; demand cycle <=60 min, sliding time < =
demand cycle.
3. Demand decimal use 4 digits,
4. Save one historical demand data,and clear the demand data when power energy save auto.
7. Multi-Tariff energy, maximum 4 tariff (TOU)
The meter can be up to 4 tariffs per days. And the time interval can be programmed by software.
Default Tariff is Single Tariff, T1.
8. Programming Password Protected
Meter must first through the password confirmation, then do the programming or other special operations.
There are two meter securities.
Level 1, for all permissions. 1122334455;
Level 2, Read only permission, 1111111111.

9. LED indicator
A high light LED is mounted on the front of the meter, it will blink/pulse at a rate proportional to the
measured load if the current through the meter more than starting threshold. The pulse value is identified
on the meters nameplate. The pulse can be used for checking the meter accuracy.
10. LCD display
The meter LCD shows 6+1 digits power consumption in kWh, without backlight. The big size of the digits
(13mm×6mm) and clearly identification of display value make meter reader easily to get the data in
distance.
View direction: 6 o'clock
Polarizer mode: Reflective (long life and UV)
