LiebeWH Ethernet Cable Tester, RJ45 RJ11 LAN Network Wire Tracker with POE NCV Testing and Digital Cable Scanning, for CAT5 CAT6 CAT7 CAT8 Cables Network Installers

[Multifunctional Network Diagnostic Tool] This professional ethernet cable tester combines 7 essential functions in one device including continuity testing power supply detection 400m length measurement port tracing fault scanning loopback testing and led illumination. perfect for testing cat5 cat5e cat6 ​ rj45 and rj11 cables it's an indispensable tool for network installers it professionals and telecom engineers working with both underground and above-ground cabling systems. [Advanced Poe Ncv Voltage Detection] The intelligent tester automatically identifies power over ethernet (poe) configurations detecting voltage levels from 1-60v with 2% accuracy. it recognizes standard/af compliant pse types and ​ poe implementations while the built-in ncv function safely detects live ac voltage in cables. safely verify ​rk>/​utp cable conditions before handling or installation. [Long-range Cable Measurement + Rechargeable] Measure cable lengths up to 400 meters with 99% accuracy without calibration and detect faults along the entire run. the built-in 1250mah lithium battery supports type-c fast charging while the included 550mah backup battery ensures uninterrupted operation. the bright led worklight enables efficient troubleshooting in dark server rooms or crawl spaces. [​ Digital Cable Scanning] Featuring ​k>-​generation digital tracing technology with three specialized modes: normal anti-interference and poe detection. the advanced ac filtering system provides clear analog signals for accurate wire mapping identifying shorts opens crosses and proper crimping of rj45 connectors. quickly trace cables through walls floors or cable bundles. [​ Identification System] Revolutionize your network troubleshooting with the unique port flashing feature that activates indicator lights on 10m/100m/1000m switches routers and hubs. the anti-interference tracing capability precisely locates network ports in crowded racks while testing cable crimp quality. save hours
