5. Working Principle
Operators generate unique 20-digit STS recharge token for users after payment. Users input the code via the meter keypad, the meter decrypts the token and adds corresponding electricity credit. The built-in metering chip continuously calculates real-time power consumption and deducts remaining credit. When the residual credit hits warning threshold, the alarm indicator flashes; credit zero triggers internal relay to cut off output power.
