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. Another way through M-bus and PC software can read power consumption

Display function:

Meters have four status: self-inspection status, cycle display status ,button press display and program status.

Communication Function:

    With M-bus COM. This meter can directly communicate the data between the meter by this port.

Pulse output function

   Smart din rail 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.
