Main Functions
1. LCD display window can display every meter information through operating key.
2. Remote communication interface can install the place where convenient for the customers to check for the
power—using information and deal with each alarm and abnormal condition timely, the longest distance is 0.5km.
3. Power-supply by the energy meter without outer power.
4. Users can finish all the functions without touching energy meter, and the system has highly anti-tamper function.

Main Features:
1. Active power measurement—Reverse current can be cumulated as forward one or measured separately.
2. Power monitor—Power consumption, balance power, voltage, current, power load, consumption history,
Max. demand etc.
3. Power over load control
4. Friendly power supply function:
Meter can be configured that it will not cut off power during night or holidays
5. Harmful appliance recognition—Meter can recognize harmful appliance (such as hot pot or heater in dormitory)
and cut off power to protect system.
6. Over—draft function
7. Pre-warning and warning function
8. Anti- tamper function
9. Event record
