## Long description

The Mastech MS6812 Digital Cable Tracker and Wire Tester with Tone Generator and Probe is a professional tool designed for installing, debugging, and maintaining telephone lines and various network or low-voltage cables. This device allows technicians and DIY users to check cable continuity and trace wires without damaging the insulation. Consisting of a sender and a receiver, the unit operates by sending a single solid tone or a dual alternating tone to the target cable, allowing the receiver to pick up the signal and assist in locating break points. It is also widely used for locating robotic lawnmower boundary wire breaks.
Advantages
This cable tracker provides a safe and non-invasive method for testing electrical paths, meaning insulation remains intact during diagnostics. It enables quick identification of telephone line states such as clear, ring, or busy. The separation of the sender and receiver units allows for flexible testing over distance, and the lightweight handheld design ensures comfortable operation during extended troubleshooting tasks.
Suitable for
Tracing telephone lines and diagnosing break points
Checking cable and wire continuity without damaging insulation
Locating robotic lawnmower boundary wire breaks
Identifying working telephone line states including clear, ring, and busy
Installing and maintaining low-voltage communication cables
When it may not be suitable
This device is not designed for tracing high-voltage electrical mains or live power cables, as it is intended for low-voltage telecommunication and signal wiring. It may also have limited effectiveness in environments with high electromagnetic interference.
Key specifications
Send tone frequency: 1.5kHz
Receive frequency range: 100 to 300kHz
Power supply: 6F22 9V batteries
Receiver dimensions: 23.8 x 4.3 x 2.6 cm
Emitter dimensions: 14.5 x 3.5 x 2.5 cm
Net weight: 234g
How to use
To use the cable tracker, connect the sender to the target cable or wire using the appropriate clips or connectors. Set the sender to output either a single solid tone or a dual alternating tone. Turn on the receiver and use the probe to follow the path of the cable. The receiver will pick up the audible tone, allowing you to trace the wire route and pinpoint locations where the signal stops, which typically indicates a break point or termination.
What to consider before purchase
Verify that your application involves low-voltage cables rather than high-voltage power lines
Ensure you have two 9V batteries available for the sender and receiver units
Assess the expected tracing distance and environment for signal interference
Always disconnect the target wires from live power sources before testing, and use the device strictly within its specified low-voltage telecommunication and signal tracing parameters.
