The invention belongs to the technical field of automatic setting and detecting and relates to an automatic multi-electricity-meter-position parameter setting and detecting method. As a multi-electricity-meter-position testing device, a mechanical arm, a main machine control unit, an in-place identifier, a mechanical arm controller, a mechanical arm claw and the like are mutually connected for communication on an electricity meter production line, full-automatic parameter setting and detecting such as electricity meter in-place judgment, grasping, barcode identifcation, parameter setting, result judging and flow-out after classification are achieved. The method can support all projects of the existing FA function test, wherein the projects comprise setting of parameters, reading and verification, switching-off and switching-on detection and the like. The mode of one-multiple parallel operation is adopted, operation electricity meter positions can be intelligently distributed, qualified products and disqualified products can be distinguished, and multi-electricity-meter parallel asynchronous operation is achieved. A setting and detection state can be displayed in real time as a display screen is arranged. A specific disqualified product recycling device can perform sound and light alarming after a groove is full of the collected disqualified products. The design principle is reliable, the automation degree is high, the application range is wide and the automatic multi-electricity-meter-position parameter setting and detecting method is friendly to environment.
