Single Phase Fee Control Smart Electric Meter is a smart metering device with special design for nation smart grid. With independent infrared, RS485, carrier communication and IC card interface, it can support for remote or local fee control function. The meter has advantages of high accuracy, good linearity, wide range and long life, which can widely used in city, country or school and any enterprise.
1. Energy Measurement:
Forward, Reversed and the sharp, peak, shoulder and off-peak combination active and reactive energy, Four-quadrant.

Timing frozen, Instantaneous frozen, Appointed frozen, Daily frozen, Measurement, Period frozen Energy.
3. Demand Record:
MD and time of the total, Sharp, Peak, shoulder, and off-peak of forward and reversed active.
MD and time of the total, Sharp, Peak, shoulder, and off-peak of combination reactive.
MD and time of the total, Sharp, Peak, shoulder, and off-peak of four-quadrant reactive.
Forward and reversed MD and time of the total Phase A, B, C.
Real-time Measurement: Measurement of Voltage, Current, Power, PF and Phase-angle.
Time Interval and Tariff: Four-kind of Tariff supported and two-set period.
4. Event Record:
missing voltage, under-voltage, over-voltage, missing phase, completely missing voltage, current/voltage phase sequence reversed, current/voltage imbalance, missing current, over-current, cover opened, terminal opened, programming, MD cleared, energy cleared, clock calibration, etc.
Manually reading: reading the data when press the up-button and down-button.
Reading by HHU(Hand Held Unit): reading the data through Infrared by HHU.
PC reading: reading the data by PC with RS485 communication port.
Reading when power off: when the power off, the meter can be woke up by the button, and then the data can be read from LCD display or by HHU automatically.
LCD display with backlight. The data can be display by pressing button or recycle display automatically.
