Choosing durable and reliable motors can reduce maintenance costs and downtime, improve the stability and reliability of the production line, and can be purchased and assembled in the market according to demand. The model of the detector 7 in the present invention is HDGC3915. The battery internal resistance tester adopts advanced AC discharge test method (this method combines the advantages of AC injection method and DC discharge method. The principle is that the processor controls the adjustable load through D / A to discharge the battery to the load, and produces a low-frequency signal through internal shunt, coupling, and filtering). It can accurately measure the voltage and internal resistance of the battery, and use this to judge the battery capacity and technical status. The user can choose the battery internal resistance test, voltage test, and capacity estimation according to their own situation as the basis for internal resistance matching when matching new batteries; the battery internal resistance is tested before and after discharge to identify the real backward battery; there are two operation modes: key operation and LCD touch; it can measure the battery in groups or single cells.
