Uni‑T UT682D Wire Tracker and Cable Locator – Ethernet & Telephone Line Tester with Tone Generator

The Uni‑T UT682D is a handheld cable locator consisting of a transmitter and a receiver designed to trace and troubleshoot telephone lines, twisted-pair LAN cables, and electrical wiring—all without stripping insulation. It supports signal tone tracing, continuity, DC voltage polarity checks, and wiring sequence verification. Ideal for network technicians, electricians, and audio/video installers, it offers fast diagnostics of cables over long distances, even in noisy environments.

Key Features:

• Multi-cable compatibility: Detects telephone lines, twisted-pair (Ethernet), coaxial, and power wires.
• Long tracking range: Up to 3,000 m phone line trace distance in open settings.
• Polarity & voltage testing: Supports DC voltage checks from ±5 V to 52 V with polarity indication.
• Open/short/wiring sequence checks: Easy identification of continuity and proper cable wiring.
• Adjustable signal output & volume: Tone generator delivers ~8 V DC; receiver allows volume tuning and includes a headphone jack for noisy environments.
• Safe and convenient: Battery-powered (transmitter and receiver each use a 9 V battery); includes low battery indication and line input protection up to ~60 V DC.
