A lead seal refers to a device similar to a lock applied by the inspector after the measuring instrument has passed the inspection. Once the lead seal is properly sealed, it cannot be opened without authorization, and the damaged lead seal cannot be reused. Generally speaking, each seal has a serial number or anti-counterfeiting mark for the convenience of management. For example, the lead seal of the electric energy meter is applied by the measurement and verification personnel after the electric energy meter is qualified. According to the "Power Supply Business Rules", forging or opening the electricity metering device sealed by the power supply enterprise to seal the electricity is an act of stealing electricity.
