Comprehensive's HDMI Cable Tester. The new CCT -01 Cable Tester was designed with the needs of the system integrator/installer in mind. When setting up or diagnosing a system the CCT-HD01 HDMI Cable Tester can be beneficial in cutting your install time in half. There are 19 wires inside an HDMI cable and only 9 of those are complete circuits. The CCT-HD01 measures each sub circuit within the cable and displays a pass/fail in the form of LED's on the front of the unit to confirm the continuity of the cable. Don't waste time running a new cable when you can check it first. The CCT-HD01 has inputs for standard and Mini HDMI cables.
