Testing principle for automotive wiring harness

The instrument computer screen can show testing result of wiring harness electric connection together, which called Conduction Testing Machine. In fact, the machine function is focus on testing each wire link open & short and failed pin and reason will be shown onto the screen easily. The instrument has no more functions except improve testing efficiency and more professional. Supposed that it has no conduction testing machine, the testing by multimeter is alternative and available as long as connection pins and conduction obey the drawing.
As above stated is electrical testing method. However, it has professional testing method for assembly dimension, Seal, Anti-aging, temperature resistance and environmental protection and so on.
