1. Alarm function: When the remaining power is less than the alarm power, the kilo watt-hour meter  often displays the remaining power to remind users to purchase electricity
  2. Data protection: data protection adopts all solid-state integrated circuit technology, and data can be kept for more than 10 years after power failure
  3. Power reminder: When the remaining power in the meter is equal to the alarm power, the power will be tripped once and the user needs to insert an IC card to restore the power supply. The user should purchase electricity in time.
  4. Automatic power off: When the remaining power in the electric energy meter is zero, the electric energy meter automatically trips and interrupts the power supply. The user should purchase electricity in time at this time.
  5. Write-back function: The energy card can write the user's accumulated power consumption, remaining power, and zero-crossing power back to the power sales system to facilitate the statistical management of the management department.
  6. User sampling check function: the power sales software can provide data sampling power consumption and provide priority sampling user sequence according to requirements
  7. Electricity query: insert the IC card to display the total electricity purchase, the number of electricity purchases, the last electricity purchase, the cumulative electricity consumption, and the remaining electricity in turn
  8. Anti-theft function: One meter and one card cannot be copied, logic encryption. Effectively prevent technical theft of electricity.
  9. Overvoltage protection function: When the actual power load exceeds the set value, the meter will automatically cut off the power, insert the user card, and restore the power supply.
  10. Low power consumption: adopting new design and SMT advanced production technology in electronic energy meter.
