|The Triplett 3256 WireMaster HDMI High Definition Cable Tester is an advanced tester utilizing X-TEST technology. It out performs similar products, identifying faults that other testers miss. The Triplett 3256 WireMaster employs both Autoscanning for quick testing of all of the wires, and Manual testing for more rigorous testing on individual wires. It works with all types of HDMI cables with Type A connectors on their ends. The Triplett 3256 will test short patch cables or long installed cables. Consisting of a Transmitter and a Receiver, the cable is easily tested by connecting to the ends of the cable and observing the LED displays. A built in battery test informs the user when the 9 volt battery needs to be replaced. Unlike other cables common in the work or household environment (coax, telephone, security, LAN, etc), HDMI cables are very fragile and can be damaged by pulling on them too hard, pulling them around corners, bending them too sharply, or just rough handling. To meet the requirements of the High Definition Multi-media Interface, some of the wires inside of the cable are very small and easy to damage. Care must be taken during installation to guarantee maximum performance of the cables. The Triplett 3256 WireMaster HDMI aids the installer by verifying that the cables are good, both before and after the installation.
