Features HDMI Signal Tester: An Essential Tool for A/V Cable Installers Avoid the problems and costly troubleshooting caused by a bad HDMI cable. This HDMI tester allows you to quickly and accurately verify HDMI and Mini HDMI cables with Type A-A, A-C or C-C connectors before installing them behind walls and in other tough-to-reach places. It's recommended for installers of digital signage applications and home theater systems who need to verify straight or crossed connections and open or short circuits. Features 2 Adjustable Test Modes: Continuity and Sweep Quickly validating whether a faulty HDMI cable is the issue in a malfunctioning application can save you time, trouble and money, as can detecting a faulty cable before you install it. The T040-001-HDMI flips from sync testing (Continuity) to step-by-step testing (Sweep) at the touch of a switch. It displays a 19 pin-to-pin wire map and shield connection status to ensure mapping continuity and proper configuration. The HDMI tester is compatible with HDMI versions 1.0 through 2.1 and cable lengths up to 164 feet (50 meters). Easy to Store in Your Toolbox and Take to the Job Site This HDMI signal tester consists of a main tester unit and a removable remote identifier that are secured in a protective carrying case when not in use. The tester units are powered by a standard 9-volt battery (not included). To test a cable that has already been installed, separate the two units and connect them to each end of the cable. One-Year Warranty The T040-001-HDMI is backed by a one-year warranty, ensuring reliability and performance.
