Main function
Measuring Function
On the EM737’S front panel, there are three LED, active/reactive energy pulse light, and alarm indicator lights .
Meter can measure import & export active energy , import & export reactive energy. The measurement type can be set
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. Its physical layers are independent with each other. One communication channel will not be affected by the other one. The meter can realize data acquisition, broadcast time setting, read, program and manage through hand-held terminals, data acquisition terminal, test equipments and computers. Communication protocols fit Modbus RTU standard.
Alarm function
When the meter connect wire wrong example: current reverse, lost phase and reversed phase sequence , 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-),9/ 11 Test pulse output contact (Q+/Q-)
The test pulse output is a polarity dependant, passive transistor output requiring an external voltage source for correct operation. For this external voltage source, the voltage (Ui) should be 5-27V DC, and the maximum input current (Imax) should be 27mA DC. To connect the impulse output, connect 5-27V DC to connector 8&9 (anode), and the signal wire (S) to connector 11 (cathode).
