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. 14/ 15 Test pulse output contact (P+/P-),13/ 15 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.
Reading the meter
The smart energy meter is equipped with 6+2 LCD display, which is used as recording consumption and can’t be reset to zero. The number system is based on units of 10. And unit is kWh.
Far Infrared interface
The far infrared communication port is on the right of LCD screen. It is infrared wireless communication port. HHU(hand held unit) can directly communicate the data between the meter and this port.The data transmission speed is 1200bps.The communication distance is not less than 5m.
Communication port
Smart meter has equipped communication port, we can program the meter’s operation data or reading via these 2 ports.(Pin26 pin27) .
Programming
The meter can be programmed by pressing button on the panel such as Modbus ID, password,Baudrate etc..
