The cable tester with RJ45, HDMI, Speakon, XLR, RCA, MIDI, USB, Micro-USB, 1/4″, Mini 1/4″  and banana socket. Simply plug the cable under test and turn the rotary switch. The LED array gives you an instant go/no-go status of each conductor path in the cable. With bullet-proof all-metal construction, it’s ideally suited to the ruff and tumble world of rock ‘n’ roll, but is also suitable for any technician working with cables. Faster and much easier than a multimeter.
