Multi-function Wire Tracker
Network Cable Tester – Professional tool for testing UTP/STP, RJ45, and RJ11 cables. Quickly checks continuity, wire sequence (1-8 & G indicators), and cable type (100M/1000M, straight/cross). Detects short circuits, open wires, and miswires, and supports shielded cable & shielding layer testing.
The wire tracker emitter (SCAN/UTP mode) helps locate target cables (BNC, network, telephone, and other metal cables) in messy wiring setups. Ideal for network engineers, IT technicians, and telecom professionals, this tester simplifies cable maintenance, installation, and troubleshooting, improving efficiency in network engineering, data centers, and office setups.
Cable Tracer and UTP Cable Test
This versatile cable tracer with RJ45, RJ11 and BNC jacks can test a variety of cables, including network cables, coaxial cables and telephone cables. Locate the cable position? Find cable faults? Measure cable length? It can do it all!


RJ45 Cable Plug Fault Test
Quickly detect the RJ45 port plug status of the Emitter and Receiver.
The status of the RJ45 cable will be displayed directly through the indicator light.


UTP Connected Swtich PD Powered Detection
UTP port support max 60V withstand voltage, the wire can betraced directlyin connection with POE switch.Emitter’s UTPcable sequence indicators will show the stasus.
Detect whether the power output of the POE switch is normal,and detect the pins used for power supply.


UTP Cable Short circuit Test
Emitter mode: The indicator lights of the short circuit pairs are flashingSwitch mode: The indicator lights of the short-circuit pairs are onAs the cable sequence show, the 5 6 core of cable are short circuit.(The other end of network cable non't connected to receiver)


Applicable to multiple scenarios
Messy Network Cable、RJ45 Plug Fault、Line Short Circuit、UTP POE Switch


Shielding Cable Conntinuity Test
“G” indicator light means the cable is normal the light off means the cable is broken


Telephone Line Status Test
- Indicator light: Off-hooke
- Indicator lighting: Standby
- Indicator flash: Ringing


Built-in Electroscope
Non-contact voltage test(NCV Mode)
Identify the neutral wire and live wire


100M/1000M Switch Detection
