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 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 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. Adopt contactless IC card (RF card) technique, waterproof, moisture-proof, dustproof, anti-wear, and anti-electromagnetic attack.
2. Mechanical wheel and LED double display, to avoid the disputes between the users and the power supply company.
3. Adopt imported components, such as single chips from USA Microchip Corp and the memory from ATMEL, which can guarantee the quality of product, more safe, reliable and solid operation.
4. One meter with one IC card and the IC cards cannot be interchangeable.
5. The IC card of different power Supply Company cannot be interchangeable.
6. Transmit data by IC card bidirectional, convenient for management.
7. In case of reverse connection, the meter still can record the used electricity to prevent illegal use of power.
8. Load identification function: when test that the malignant load power exceeds the alarm power (can be adjusted, generally it is 300W), the meter will switch off to stop power supply and after 6 minutes the meter will automatically switch on to supply power again (the meter with load identification has such function).
