UNI-T UT685B KIT TDR Cable Tester with Wire Tracking Receiver

UNI-T UT685B KIT TDR Cable Tester in Sri Lanka

Handheld TDR Tester with Wiremap and Wire-Tracking Receiver

The UNI-T UT685B KIT TDR Cable Tester delivers precise Time Domain Reflectometry (TDR) diagnostics for twisted-pair, coaxial, and telephone cabling. It is designed to assist network engineers in Sri Lanka with measuring cable length, locating opens and shorts, identifying split pairs and crossed wires, and verifying PoE supply on network cabling up to 500m.

Featuring an integrated RJ11/RJ45/coaxial F-connector design with no adapters required, a 2.8" backlit LCD, and a bundled UT683R wire-tracking receiver, this instrument streamlines structured cabling installation, PoE verification, and cable fault isolation to help prevent unexpected network downtime.

Technical Specifications

Cable Length Range: Up to 500m | Accuracy: ±4% or 0.6m (whichever is greater)

Blind Spot: Approximately 0.3m (no blind area on measurement)

Supported Cables: Twisted-pair (Cat5e, Cat6, Cat6A, Cat8), coaxial cable, telephone cable

PoE Standards Detected: IEEE 802.3af, IEEE 802.3at, IEEE 802.3bt (up to 70VDC)

Display: 2.8-inch LCD with backlight and ft/m unit switching

Voltage Detection: Alerts on live cable voltage ≥10V (AC/DC), with polarity indication

Key Features

Testing Modes: TEST mode (TDR length & fault detection), SCAN mode (tone/wire tracking), and POE mode (power standard identification)

Wiremap Diagnostics: Detects open circuit, short circuit, crossed wires, crossed pairs, and split pairs with on-screen wiremap display

Integrated Ports: Built-in RJ45, RJ11, and F-connector ports — no external adapters needed for standard cable types

Bridge Tap Detection: Identifies bridge gaps and distance-to-tap on telephone networks wired in star or bus topologies

NVP Calibration: Adjustable Nominal Velocity of Propagation for improved length measurement accuracy on specific cable types

UT683R Receiver (Kit Exclusive): Adds cable tracking, NCV (non-contact voltage) detection, and built-in flashlight, with Micro USB rechargeable battery

Power: 3 x 1.5V AA batteries with auto power-off (10 minutes in test mode, 60 minutes in tracking mode)

Build: Compact 181 x 80 x 39mm housing (~360g) with carrying bag for field technicians
