Main functions
*Timing function
The real-time clock chip is built in the meter, so the meter can display calendar and clock. The clock within the meter still can normally work when power is off.
*Multi-rate electric energy measurement function: 24 hours in a day can be divided into 8 periods of time at most, and different rates is charged for different periods. Four tariffs can be set at most, which are T1, T2, T3 and T4 respectively. The Consumed energies under different tariffs are counted into the corresponding electric energy registers, which are E1, E2, E3 and E4 respectively. When the actual tariff quantity is less than four, the corresponding electric energy values under those tariffs can be shielded from displaying.
* Power consumption control function:
Through adopting IC card, the power consumption data of the users and control information of electricity vending system can be mutually transmitted between the meter and the vending system under power supply management departments to realize the functions of meter reading and electricity charge payment. When the available energy in the meter is consumed, the meter will automatically turn off power; only when the users pay off electricity charge, and the new available energy in IC card is input into the meter, can the meter resume to supply power.
