Description

This professional-grade network cable tester makes troubleshooting Ethernet and telephone lines simple and efficient. Whether you’re a network technician, IT professional, or home user managing your network infrastructure, this RJ45 line tester helps you quickly identify connection problems, trace cables through walls and ceilings, and locate breakpoints without stripping cable insulation. The two-piece design separates into an emitter and receiver unit, making it easy to test long cable runs up to 300 meters independently.

The ethernet meter features high-sensitivity circuitry with strong anti-jamming protection, ensuring accurate results even in electrically noisy environments. Test for open circuits, short circuits, miswiring, and incorrect pin sequences on RJ11 telephone cables, RJ45 network cables, and other metal wiring. The receiver’s adjustable volume control and bright LED indicators help you identify the target cable among bundles of wires, while the built-in LED light makes working in dark spaces like server rooms and cable closets more convenient. Complete with all necessary adapters and cables, this line finder tool is essential for network installation, maintenance, and troubleshooting tasks.

ADDITIONAL INFORMATION

Safety & Usage Guidelines: This line tester is designed for testing unpowered or low-voltage cables only. Never use this device to test live power lines, high-voltage circuits, or any cables carrying heavy electrical current, as this may damage the unit or cause safety hazards. Always power off equipment before testing to ensure accurate readings and device safety.

Battery Information: Requires two 9V batteries (not included in the package). The low power consumption design provides extended battery life, with automatic power-off protection to conserve battery when not in use. Replace batteries when LED indicators become dim or audio signals weaken.

Storage & Maintenance: Store the tester in a dry environment away from moisture and extreme temperatures. Clean the exterior with a soft, dry cloth. Keep RJ11 and RJ45 connectors free from dust and debris for optimal connection quality.

Application Environments: Ideal for telecommunications network installation and maintenance, computer network wiring projects, CCTV security system installations, office network troubleshooting, home network setup, and routine cable maintenance across residential and commercial properties.

Compatibility Note: Works with standard twisted pair Ethernet cables (Cat5, Cat5e, Cat6) and telephone cables (RJ11). Can trace cables connected to active network devices like switches and routers operating at low voltage. Through the included alligator clip adapter, can also trace other metal wiring systems.
