Realization of automotive wiring harness Tester

Dude, what age are you from? How to use such primitive equipment now? Now there is a special pneumatic test-bed. First, input the conduction relationship of this wire harness into the computer, and then connect the connector of the wire harness to the corresponding module on the test bench for one-button test. If there is any short circuit, open circuit or path error, the computer will display the test error, and the machine that prints the label and barcode will refuse to print. It is convenient and quick to print only after the conduction is qualified. 30 seconds to detect a quite responsible car dashboard harness.
