    1. The user buys electricity and inserts the card into the electricity meter. Normally, the buzzer sounds long, the purchased electricity is input into the meter, the relay is switched on, and the alarm light is off. The meter has an electrical output.

    2. After the user purchases the electricity card and inserts it into the electricity meter, the buzzer of the electricity meter does not sound long, the power is not input into the electricity meter, and the display items of the electricity meter are displayed in turn. The reason is that the electricity meter has not been issued. Contact the branch office to install the meter and re-insert the key to modify the card.

If the incoming line, outgoing line and neutral line are completely correct and there is electricity in the circuit. If the meter is faulty, please contact the branch office to install the meter to deal with it.

    1. Retrieve the original electricity card of the meter.

    2. Contact the branch bureau to install the watch handling.

    8. The electricity meter displays E-19. When the electricity meter appears E-19 and power off, it is overload power off. Approach:

    1. Check the household load, if the load exceeds the maximum load setting of the meter, go to the business hall to apply for capacity expansion and meter replacement.

    2. If no load is added and the meter still frequently appears E-19, check the meter wiring to see if the live wire is shorted to ground.

    9. E-14 appears in the power meter, the number of power purchases on the card is inconsistent with the number of power purchases on the meter. Contact the branch bureau to install the watch and reset the watch and card.
