HOW TO USE
1. The user takes the IC card to the electric power administration department (or the electric power sales office) and pays for the electric power firstly, then the staff of the electric power administration department inputs the relevant data of purchased electric power into the IC card through software and IC card reader-writer.
2. User takes back his IC card and then swipes it on the induction area of the energy meter (contactless IC card energy meter) and the data of purchased electric power will be automatically input into the energy meter.
3. After the energy meter receives the information, it will switch on and the electric power will be supplied.
4. When the remaining power amount is equal to the alarm amount, the energy meter will alarm by power cut. The user can use the remaining power amount by swiping the IC card again on the energy meter, and when the remaining power is used up, power will be cut again and the user shall buy electric power again.
FUNCTIONS
1. Prepaid function: collect the bills in advance, it will automatically cut power when the purchased power amount is used up.
2. The way of power cut: by inside/outside switch. For outside switch energy meter, it must connect with AC contactor or air switch, the energy meter control on-off of the load current by controlling the AC contactor or on-off of the air switch coil current.
3. Memory function: data in the meter can be stored for 10 years when the power is failure.
4. Display function: double display, the mechanical wheel displayer shows the used amount of electric power; LED/LCD displayer shows the remaining power amount and other information.
