Main function :
Measuring Function
On the EM425’S front panel, there are three LED, respectively, for the Active energy pulse light, current reverse ,communication .
The smart energy meter is equipped with 6+1 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.
Display function
Meters have two status: self-inspection status, cycle display status
Self-inspection status:
Cycle status:
Meter display as follows: active energy, id, Serial number. Display cycle is 3 seconds.
Pulse output function
Energy meter is equipped with a pulse output which is fully separated from the inside circuit. That generates pulses in proportion to the measured energy. They are test pulse output (pins 11 & 12). Usually, the test pulse output is used as testing accuracy or reading purpose in close quarters.
