• 【All-in-One Testing】 This RJ45 network cable tester supports continuity check, wiring diagram detection (open/short/crossed/reverse), and high-precision length measurement. Dynamic calibration ensures up to 97% accuracy. When faults occur, the screen displays the exact length range of open or short circuits for quick breakpoint location.Compatible with Cat5/5e/6/6e cables
• 【8 Remotes for Multi-Cable Testing】 Comes with 8 individually numbered remote units, allowing simultaneous testing of up to 8 network cables. Ideal for server rooms and complex wiring environments—each remote has a unique number for easy cable identification, eliminating back-and-forth movement and boosting efficiency
• 【TDR Technology】 Advanced TDR (Time Domain Reflectometry) technology precisely measures cable length and pinpoints open or short circuit fault distances. When abnormal pairs are detected, the screen clearly displays both normal and abnormal pair lengths, providing reliable data support for network troubleshooting
• 【Large LCD Screen 】 Compact and lightweight design integrates all functions into one portable unit. Built-in long-life battery provides over 50 hours of standby time, reducing battery changes and ensuring continuous operation. Large LCD screen displays test results clearly for easy operation
• 【Auto Calibration 】 Self-check calibration automatically compensates for battery level or temperature changes, ensuring stable and reliable testing every time. Auto power-off saves energy. Efficient and reliable for one-person operation—ideal for network cabling, maintenance, and troubleshooting
