[0003] The detection instrument needs to be detected regularly to ensure its accuracy. Currently, the verification and calibration of the gas detector need to be carried out in a designated laboratory, which causes long travel, long time, long cycle, high cost, and more importantly, the problem cannot be found immediately, which poses a serious hidden threat to the users or producers. Moreover, the instrument using team cannot operate and record the data of the instrument verification and configuration due to the differences in operation and management of the laboratory to which the instrument is sent.

[0004] Currently, the verification and calibration operation of the laboratory is mainly carried out on a single machine, and the technical personnel manually operate the machine. Moreover, the process is complicated. When multiple machines need to be detected, the operation is slow, the gas in the gas cylinder is wasted, and the operation is prone to errors, which may even cause missed detection, reduces the accuracy of the verification, and brings great safety hidden danger to the users.

[0005] When the detection environment changes, the corresponding parameters of the gas detector need to be set to ensure the normal operation of the instrument. However, sometimes, a large number of parameters need to be set, and manual operation is very tedious, time-consuming, and prone to errors when multiple machines need to be set.
