Frequently Asked Questions

How to Use This Device

The Network Cable Tester is simple to operate. First, insert a 9V battery into the master unit. Connect one end of the cable to be tested into the appropriate port (RJ45 or RJ11) on the master unit. Connect the other end of the cable into the corresponding port on the remote unit. Turn the power switch to 'ON' for a standard test or 'S' for a slower, more deliberate test. Observe the LED sequence on both units to identify any faults. The LEDs will light up sequentially if the cable is wired correctly.

Maintenance and Care

Maintaining the cable tester involves keeping the units clean and dry. Avoid exposing the device to extreme temperatures or moisture. When not in use, ensure the master and remote units are interlocked to protect the ports. Remove the 9V battery if storing the device for extended periods to prevent leakage. Regularly inspect the ports for any debris or damage. A clean tool performs better.

Diagnosing Common Faults

This tester effectively diagnoses several common cable faults. If an LED on the master unit lights up but its corresponding LED on the remote unit does not, this indicates an open circuit or a broken wire.
