Main function:
Measuring Function:
Meter can measure import & export active energy , import & export reactive energy.
Display function :
Smart meter have two status: cycle display status andbutton press display .When pressing the button, User can set according their request. Button press will Backlight the LCD. Display cycle can be set within 5~20 seconds, The default is 5 seconds.
Electricity parameters measurement and monitoring :
Measure record and display voltage, current, power and power factors. error is not more than ±1%.
Communication Function :
With an infrared COM and a RS485 COM. Communication protocols fit Modbus RTU standard. RS485 communications transfer rates allow selected at 1200bps, 2400bps, 4800 bps and 9600bps, default is 9600bps.
Alarm function:
When the meter connect wire wrong example: current reverse, the meter will display , the ALARM led will be on.
Pulse output function :
Smart meter is equipped with a pulse output which is fully separated from the inside circuit. That generates pulses in proportion to the measured energy .include the testing pulse output of active energy and reactive energy. 8/ 11 Test pulse output contact (P+/P-).
