1.With two-way measurement of the function,  the metercan accurately measure the positive and negative direction of the active energy, and in one direction, with anti stealing function,and will return the information to the electricity sales management system at the time of the next purchase.

2、Use IC card and with advanced encryption technology to ensure a table of a card. Users buy their own electricity, do not have access to meter reading, charges, the implementation of electricity after the first purchase.

3.The meter is based on the amount of electricity used, according to the power unit price per 1 degree deduction, the remaining amount of the table to retain a number of decimal to ensure that the interests of users without loss.

4.Electric meter to measure the amount of electricity-based, according to the electricity price per unit of electricity deducted, the remaining amount of the table to retain multiple decimals to ensure that the user's interests are not lost.

5.Double alarm prompt function, when the user pre-order amount used up when the remaining amount is less than the display alarm amount, the meter as a visual warning. While the remaining amount is less than the amount of windshield alarm, the trip power to remind the user to buy electricity.

6.LCD screen rotation shows the cumulative electricity consumption, the remaining amount of electricity unit price.

7.Has a perfect multi-fault self-test function, in the event of a special fault, the meter displays the appropriate notice to remind users to troubleshoot.

8.Using a new high-current magnetic retention relay, low power consumption and high reliability.

9.The use of electrical isolation technology output power meter pulse signal, light-emitting diode instructions electricity, stable, reliable, long-term work does not require adjustment.

10.With reliable power-off protection, the data will not be lost after the power is off. The data will remain unchanged for 100 years and will resume after power-on.

11.IC socket self-protection function, when the metal sheet and other foreign substances into the IC socket, the card reader part of the automatic protection but does not affect the normal measurement and other functions to ensure that the watt-hour meter will not be damaged.
