The device is powered by lithium battery. Some unit circuits are combined to meet the need of different type of cables, and the cable type is selected by touch screen. The embedded development board sends the detecting instruction to the MCU control circuit to detect the cable with the cable detection circuit. The detection results are displayed on the touch screen. The equipment composition is described in detail, and the detection method is showed through an example. The field application shows that the device has the advantages of high detection speed, high accuracy rate, small volume and strong expandability.
