About this item

• ⭐【Revolutionary Network Cable Tester】NF-8509 Network Tester Combines network and cable tester and multimeter functions. The multimeter functions include DC/AC current, DC/AC voltage, resistance, NCV, continuity, diode, temperature measurement. Ethernet Cable Tester is easy to accurately locate the target cable, widely used in engineering wiring, network and equipment maintenance
• ⭐【New Upgraded Multifunctional Network Tester】This cable toner has functions of POE tester, anti-jamming RJ45 CAT5 CAT6 cable tester, continuity tester, multimeter voltage test, port flashing, sensitivity adjustment, cable length test and LED flashlight.
• ⭐【Time Domain Reflectometry (TDR) 】The NF-8509 Cable Tester is a portable Time Domain Reflectometry (TDR) cable length tester. It measures cable length, calibrates Velocity of Propagation (VoP) values, finds the distance to faults in cables, convenient real-time on-site measurement
• ⭐【POE Tester】Quickly identify PoE device, Poe tester can test the information of standard PoE devicesuch as POE voltage,power supply polarity,power supply mode and also the type of PSE (af or at standard ). Automatically detects and switches between 10M/100M/1000M modes
• ⭐【PORT FLASH】Quickly & Exactly find out the target cable port to improvework efficiency. lf there is a port whose flash frequency is same as the“Length/Flash”port on tranmitter,the frequency is around 3 secsalso the other ports are flashing more quickly,then you can easily identify it is your target port.
• ⭐【NCV Non-contact Measurement + Intelligent Anti-burning】The network tester is close to the place where there is an AC signal, and the multimeter will send out an alarm. The Ethernet tester automatically recognizes the measurement object, and can intelligently prevent burning at 250v voltage to prevent the wrong operation from burning out the element Devices, more secure and safe to use
