 Functions and Features:

1  Active energy measurement, and needn't calibrate under long term working status;

2  Use a dedicated large-scale integrated circuits and SMT surface mount technology, which have the characteristic of advanced technics and   

Simple structure;

3  All the electric component of the meter are long life and high reliability, so the meter have the characteristic of long life and high reliability;

4  Wide temperature LCD display: 5 integers and 1 decimal;

5  Built-in high performance 485MHz wireless module, and the opened communication distance can achieve 1.5KM;

6  Can read the meter's storage electricity data and configure the meter's parameter through infrared, RS485 interface and wireless module;

7  Phase wire current and neutral wire current sampling at the same time, and can fully avoid stealing the electricity through L and N (anti-tamper electronic meter have this function);;

8.    Built in magneticlatching relay, which can control the switching on /off through infrared, RS485 abd wireless communication;

9.    Can be automatically checking present relay's status, and have the power off indicator display;

10.  Can set the electric meter to ordinary mode or prepayment mode, and realize the switch of prepayment function;

11.  Can freeze the electricity amount of last month and the month before last month, freezing electricity amount of meter's reading date and freezing electricity amount of end of month, which can be realized through infrared, RS485 interface and wireless module
