USB Cable Tester Charging Cable Test Card Type-c mini USB Micro PCB Board Data Wire Test Card

The test card supports Type-c, mini usb, and Micro USB three interfaces, which can test the open circuit, short circuit and wire welding error of the USB data cable.

Instruction 1. Connect a 5V power supply or power bank to the Micro usb power interface, plug one end of the USB cable to be tested into the USB interface, and the other end into the corresponding interface, press the reset button on the test board, and the tester starts to work. 2. The 4 LED lights on the tester will light up. If the lights do not light up, it means that the signal line has an open circuit fault. Then the LED lights will light up in sequence from left to right. If the lighting sequence is disturbed, it means that the wire has a faulty welding reverse. 3. If there are 2 LED lights lit at the same time when they are lit in sequence, it means that the two lines have a short circuit fault. 4. The buzzer will emit a "beep" sound, and the last four lights will light up again, and the test is completed.
