The VDv Distance Meter determines cable length automatically up to 1500 ft. (457.2 m) on most cables with ± 5% accuracy and ± 1 ft. (0.3 m). It also includes a Cable Fault Finder that determines if cable run is broken or damaged. In addition, the cable manager measures cable remaining in a box or on a reel. This also simplifies cable estimating and helps you bill jobs more accurately. Measurements can be switched between metric and imperial units.
