Purpose:
--Accurate measurement of residential user data with anti-theft function;

Main functions:
--Measure active power, four quadrant reactive power, apparent electrical energy, power factor, reference voltage, reference electricity, load curve, electricity theft records, etc;
--Multiple rate: programmable billing based on six time zones;
---Communication: RS 232, optional (IEC 62056-21) or IR interface;
--Advanced anti-theft features, capable of recording electricity theft events and data information of electricity theft points;
--External magnetic field effect: When the external magnetic field is ≤ 0.2 T, it can resist the magnetic field effect; When the external magnetic field is greater than 0.2T, it can be detected;
--Resist high voltage 35 kV spark discharge;
--Anti mobile phone interference;
--Open lid record;
--Reverse current;
--Load grounding;
--Anti zero line interference (variable resistor/capacitor, diode, AC/DC conversion signal);
--Single line operation, accurate recording;
--The electricity meter adopts large-sized LCD display, backlight, automatic display mode and button display mode;
--Meter display/power-off communication;
--Ultrasonic welding of electric meter casing;
