Verification of audio, data, and video cables.

This is an easy-to-use cable tester that verifies the integrity of metal cables commonly found in industrial voice/data and video equipment, including telephone wiring, data networks, and video/security cables, both domestically and commercially. The M749GM-9111G incorporates cutting-edge technology and offers features not available in previous cable mappers. Its advanced wire map engine instantly and accurately displays complex wiring faults, and the TDR (Time Domain Reflectometry) detects fault locations, enhancing on-site productivity.

basic information

Accuracy The main product, M749GM-9114G, accurately measures cable length using TDR and displays the distance to the fault location. TDR sends a signal into the cable and measures the time it takes for the signal to reflect back after the impedance changes due to damage, disconnection, or short circuit in the cable. The recorded time is converted into an accurate distance value. TDR helps identify the location of cable faults. This not only speeds up fault detection but also minimizes disruption to equipment and components and potential damage.
