Function and features
1. Owning forward and reverse direction metering function, besides,
it can accumulate electric quantity in one same direction, that is, calculation
reverse electric quantity into forward direction.
2. The electric quantity adopts displaying, of which there are five
integer-places and two decimal-place while also can be six integer-place and one
decimal-place, its unit is kilowatt-hour, making record of accumulated total electric power
consumption.
3. When electric energy meter is communicated with external
equipments, the communication indicator lamp would be brightened, which stands for
that the electric energy meter stays at communication state.
4. Own passive isolated type electric energy impulse output
terminal, the impulse output is square wave, and the impulse width is not smaller than 80ms±20%.
5. The parameter programming (RS485 or the infrared programming,
setup , reading meter) be able to setup the number (address) of
ammeter, active electrical energy initial reading, the password and
so on
Advantages:
