Omnitronic LH-089 Information The Omnitronic LH-089 is a cable tester that can be used to test a variety of audio and data cables. It is a versatile tool that can be used by musicians, sound technicians, and other professionals who need to ensure that their cables are working properly. The LH-089 has a split chassis design that allows it to be used to test long cables that are installed through walls or ceilings. The transmitter module plugs into one end of the cable, and the receiver module plugs into the other end. The two modules communicate with each other using a wireless signal, so there is no need to run a long cable between them. The LH-089 can test a variety of connectors, including XLR, jack, DIN, RCA, speaker, RJ45, RJ11, BNC, and banana. For each connector, the LH-089 individually tests each pin and displays the results on a LED display. The display also shows the test speed, which can be set to fast, medium, or slow.
