I am interested in testing some low voltage cables for their quality. For example, USB, audio and Ethernet cables.
Testing continuity is simple, but I want to know if these cables may momentarily disconnect when stressed, such as when bent.
The ideal indicator would be like the buzzer from my multimeter which I can hear a sound with continuity only that I want to hear a sound when there is an open circuit. Is it something that I can add to my multimeter to test for short period of open circuit? It would be even better if I can use it to test headphone cable (without having to cut the cable, of course).
