Cable Tester for Coax Mapping

The Klein Tools VDV512-100 tests and maps coaxial cable runs with simple push-button operation. It is built for installers and technicians who need to verify wire continuity and identify faults quickly. An easy-to-read LED panel displays PASS, OPEN, or SHORT conditions for immediate diagnosis. The unit includes Remote #1 to begin testing right away.

Included Remote and Optional Expansion

Remote #1 (red) ships in the box so a single technician can trace and map one cable immediately. Color-coded push-on remotes support testing up to four cables when purchased separately. An upgrade kit VDV512-110 adds a holder with four remotes and an F adapter for larger mapping jobs. The tester runs on two replaceable AAA batteries.

Suited for Coax Verification, Not Multi-Wire Suites

This tool suits professionals and DIYers who need straightforward coax continuity checks and mapping. Buyers who require testing of twisted-pair data cables, telephone wiring, or fibre optics should look at a different instrument. Users needing more than four simultaneous cable IDs must purchase additional remotes or the upgrade kit. The device focuses solely on coaxial cable faults.
