3.Basic Features
3.1 Measuring positive & negative active energy with negative energy accumulated into positive energy,.
3.2 The meter also display real voltage , real current , real active power
3.3 Pulse LED indicates working of meter£¬Pulse output width 80+-20ms
3.4 Measuring active energy without calibration under long term operation
3.5 display step by step with button
3.6 it can use APP software for data reading and remoter control on/off.
3.7 it has timing control function , it can set value from APP
3.8 it can control on/off by hand through the button
4.Working principles
Single phase voltage and current are sampled from respective sampling circuit and transformed into suitable signal, which is carried into integrated circuit , then the meter output pulse signal in positive appropriation to measured power to drive LCD counter to realize energy measurement. The meter has energy pulse output for testing with pulse width of 80+20ms
5. Structure
The meter consists of meter base , meter cover , terminal base , terminal cover . there are lead seal on meter coverand terminal cover . A special screw is used to fix the terminal cover on which a lead seal can be installed
