[0002] With the gradual improvement of my country's socialization and the gradual rise in people's living standards, owning a car has gradually become a standard configuration for urban families. Therefore, there are more and more gas stations for refueling cars.

[0003] However, some gas stations have the problem of inaccurate refueling, deliberately adding less or missing gasoline. The cheating technology of gas station pumps is becoming more and more sophisticated, and the cheating methods are becoming more and more covert. The traditional mechanical cheating methods such as privately removing the lead seal to adjust the mechanical adjustment device of the flow measurement converter, or installing a return oil pipe on the oil pipeline, or replacing the gear on the counter main shaft have gradually developed into high-tech cheating methods such as replacing the gas station motherboard with a computer cheating program, or privately modifying the circuit on the motherboard, replacing the metering chip, or connecting to the computer programming through the reserved interface on the motherboard. Every year, a large number of complaints received by the Quality Supervision Bureau involve inaccurate metering at gas stations. Therefore, the staff of the Quality Supervision Bureau needs to frequently conduct calibration tests at multiple gas stations.

[0004] In the prior art, supervisors often arrive at each gas station and then install standard metal measuring instruments for testing, which takes a lot of time to install the equipment, greatly reducing the efficiency of calibration testing.
