The UNI-T UT683 Kit is an intelligent wire tracker designed for locating and identifying cables without damaging the insulation. It consists of a transmitter (UT683T) and a receiver (UT683R) and is often referred to as a Network Cable Tester, Wire Tracer, or Cable Tracker Kit.   

Features:

The UT683 Kit is built with strong anti-interference capabilities, allowing for accurate cable tracing even in complex wiring environments.  

Wire Tracking: Enables quick and accurate location of target cables within a bundle or behind walls. The receiver picks up the signal transmitted by the transmitter connected to the cable under test.   
Line Alignment: Helps in identifying corresponding wires within a multi-core cable.
Open/Short Circuit Testing: Can automatically identify open or short circuits in cables (up to 10 kΩ).   
Polarity Testing: Allows for checking the polarity of telephone lines.   
Port Flashing: The transmitter can make the port light on connected network devices blink, aiding in identification.   
NCV (Non-Contact Voltage) Detection: The receiver often includes an NCV function to detect the presence of AC voltage without physical contact, enhancing safety.   
RJ45 and RJ11 Connectors: Supports testing and tracing of both network (Ethernet) cables with RJ45 connectors and telephone cables with RJ11 connectors.   
Headset Jack: The receiver usually has a 3.5mm headset jack for noisy environments, allowing the user to hear the tracing signal more clearly.   
Low Battery Indication: Both the transmitter and receiver typically have low battery indicators.   
Rechargeable Battery: Powered by a built-in rechargeable lithium battery for extended operating time.   
Robust Design: Comes with a carrying case for easy storage and portability.   
Applications:

The UNI-T UT683 Kit is a versatile tool for various applications, primarily in network and telecommunications, but also in electrical maintenance:

Network Cable Installation and Maintenance:
Tracing network cables in offices, homes, and industrial settings.
Identifying the correct cable among a bundle connected to patch panels or switches.
Verifying cable continuity and identifying breaks or short circuits.   
Troubleshooting network connectivity issues caused by faulty cables.
Telephone Line Installation and Repair:
Tracing telephone lines within walls or distribution boxes.
Identifying the correct telephone line for connection or repair.
Checking the polarity of telephone lines.
General Electrical Wiring:
Tracing low-voltage wires in specific applications (though not designed for high-voltage systems).
Identifying specific wires in control panels or low-voltage circuits.
DIY and Home Improvement:
Tracing speaker wires, alarm system wires, or other low-voltage cables during home renovations.
Identifying faulty cables in home networks or telephone systems.
 
UNI-T UT683 Kit is a valuable tool for IT technicians, network installers, telecommunication engineers, electricians, and even DIY enthusiasts who need to efficiently and safely locate and diagnose issues with network and telephone cables. Its ability to trace wires, test for faults, and identify polarity makes it an essential instrument for cable management and troubleshooting.
