2. The user inserts the pre-purchased power IC card into the meter in the direction of the arrow on the card (the metal contact points to the left). The display first displays F1 and then the current power purchase, and then displays F2 stably and then the display displays the original remaining power plus the new purchase The sum of the power is the current remaining power. At this time, the IC card can be removed and the display goes off. (If the remaining power in the table is lower than the displayed alarm power, the display is always on. When the sum of the original remaining power in the table and the power in the purchase card is greater than 9999kWh, the power in the card is not entered into the meter and is still stored in the card.

4. In the normal use of the pre-paid meter, it will automatically reduce the amount of electricity purchased. When the remaining power in the energy meter is less than 20 degrees, the display shows the current remaining power to remind the user to purchase electricity. When the remaining power is equal to 10 degrees, the power failure reminds the user to purchase electricity once. At this time, the user needs to insert the IC card into the energy meter to restore the power supply. When the remaining power is zero, the power supply is stopped.

7. Every time the user inserts the IC card into the pre-paid meter, the meter will write all the user's electricity consumption on the IC card. When the user next purchases electricity, the electricity sales management system reads the IC card data summary and checks whether the user is legal Electricity. The electricity inspector can also use the inspection card to check the user's electricity consumption.
8. The power supply management department sets the user's maximum power consumption load according to the actual situation. When the actual power load exceeds the set value, the power supply is stopped and the meter display shows "E2" to remind the user to reduce the power load.
