    Common faults
    Device does not display
    The nixie tube does not display anything, or does not display the user information to be inquired
    1.1 reasons
    1.1.1 fuse is blown.
    1.1.2 the power transformer on the control board is faulty.
    1.1.3 IC card is too dirty or inserted reversely. Wipe the IC card and insert it. If the problem is not solved by the above method, it is necessary to open the back cover of the integrated circuit controller, insert the management card, press the reset button to reset, and input the relevant information to the IC card again.
    The device shows that there is electric energy. But the output is dead
    2.1 reasons
    2.1.1 dz-48 coil of the device is burnt out.
    2.1.2 terminal block wiring is loose.
    2.2 troubleshooting
    2.2.1 check whether the dz-48 coil of the device is burnt, and repair or replace it if it is burnt.
    2.2.2 use a screwdriver to tighten the screws of the terminal block to ensure good wiring.
    The device shows zero electrical energy. But no tripping.
    3.1 reasons
    3.1.1 the dz-48 coil of the device is burnt out or the neutral line is open circuit, so that it will not trip when it should trip.
    3.1.2 the lead of terminal strip is loose.
    3.2 troubleshooting
    3.2.1 check whether the dz-48 coil of the device is burnt or whether the neutral line is open. If it is burnt or the neutral line is open, replace or connect it properly.
    3.2.2 screw up the terminal block screws to ensure good wiring.
    The electric energy constant does not match the number displayed on the computer
    4.1 reasons
    4.1.1 the constant of electric energy meter and IC card is inconsistent.
    4.1.2 the position of sensor head and dial of photosensitive sensor is not appropriate.
    4.1.3 the aluminum plate surface of the electric energy meter is dirty, which causes the sensor to misread and mistransmit.
    4.2 troubleshooting
    4.2.1 modify the constant of IC card to make it consistent with the constant of electric energy meter.
    4.2.2 open the meter cover, adjust the position between the sensor head of the photosensitive sensor and the dial, so that the revolution of the electric energy meter is consistent with the photosensitive pulse.
    4.2.3 wipe or clean the dirty spots on the dial so that the sensor can conduct normal readings.
    1. IC card meter has a variety of anti stealing functions, with small starting current, no creep, wide load, low power consumption, straight error curve, good stability in long-term operation, beautiful appearance, small volume, light weight and convenient installation.
    2. Pre purchased power: IC card transfers data to realize data read back, including: read back total power, remaining power, accumulated power purchase in the meter, total power purchase times and other information.
    3. High accuracy: IC card meter is designed by full electronic type, with imported special chip built in, the accuracy is not affected by frequency, temperature, voltage, high-order harmonic. Long life: SMT technology is adopted, optimized circuit design, the whole machine does not need to adjust the circuit after leaving the factory.
    4. Technical parameters: long life base meter is adopted to extend the period of IC card meter.
    5. If the power is overloaded, it will automatically alarm the power failure and residual power alarm to remind the user to purchase power in time.
    6. Low power consumption of IC card meter: it adopts low power consumption design to reduce power grid line loss.
    1. With IC card ammeter, manual meter reading is not necessary, which is conducive to modern management. The use of IC card electricity meter avoids many inconveniences brought by manual meter reading and door-to-door charging to customers, and the historical power purchase data can be saved, which is convenient for customers to query.
    2. It fully embodies the commodity attribute of electric power. To purchase electricity before using it, customers can purchase and use electricity in a planned way according to their actual needs, without any late fees and unnecessary expenses.
    3. IC card electricity meter not only solves the problem of charging difficulty, but also solves the charging problem of scattered residential customers, temporary customers and customers who often owe fees.
    The payment is not convenient. You must pay at the self-service payment point or the business hall of the power supply bureau. After the payment, the card should be inserted into the electricity meter again, and the electricity meter can read the charge and send the electricity. You can also pay online, but you still need to insert the card into the self-service payment point after payment, and the fee you pay will be on the card, which is very inconvenient. If you don’t have electricity at home at night, you have to go out and pay with a card.China Single Phase Electric Power Meter factory
