1. Signal transmission format: multi-frequency pulse signal 2. Output level: 8Vp-P 3. Connector type: RJ11, RJ45 4. Compatible network cables: CAT5, CAT6 5. Network cable compression detection speed: 1 second 6. Signal transmission distance: 3 kg 7. Input voltage protection: 60 V 8. Network cable detector: detects shielded and unshielded network cables on switches, routers, and other devices operating at less than 60 volts or without power. 9. Phone line finder: finds phone lines connected to powered or unpowered devices. 10. Auto-power off: automatically shuts off after 30 minutes. 11. Power supply: 9V 6F22 Battery 12. After completing the cable search, you can directly perform operations based on the line sequence (including open, short, open, and crossover), improving work efficiency. 13. Primarily used for quickly detecting through-hole faults, locating fault points, and marking lines. It can also be used to quickly determine if a fiber is broken, excessively bent, or poorly connected. 14. Fast and accurate cable location. Adjustable sensitivity allows for quick identification of the desired cable in cluttered environments. 15. Compatible with 48-core network cables, coaxial cables, telephone cables, and shieldedunshielded network cables. 16. Quickly troubleshoot line faults and locate breaks, shorts, or damage in cables. Place the receiver probe close to the cable. If you hear a "clicking" sound, this is normal. Move along the cable. If the sound stops, the line is broken. 17.
