Klein Tools’ VDV distance meter for pair-conductor cables measures voice, data, video, doorbell, siamese, lamp-wire and NM cable length up to 1,500 ft. and locates faults, in addition to simplifying inventory, estimates and billing jobs. It has six preprogrammed nominal cable length constants for RG-59, RG-6 and RG-11 coaxial as well as Cat 3, Cat 5e and Cat 6 twisted-pair. Users can adjust the capacitance/foot constant based on the cable being tested. This tester also ensures compliance and identifies cable runs outside specification. The fault finder feature determines if a cable run is broken or damaged.
