Q: What is a cable tester?

A: A cable tester is a device used to test the signal strength or connection for a type of cable or network of cables.  There are many different types of cable testers and each test specific cable or several different types.

Q: What does this product test?


  • Crossed wires

  • Connectivity

  • Open circuits

  • Crossed pinning or straight through

Q: What are different types of cable testers?

A: Verification – A cable tester can verify whether or not the cables wired are properly connected and paired.  This type of tester will reveal any problems in the cables.

Qualification – These types of testers cover everything that the verification equipment test but they will also tell you how well the cable supports data transfers.

Certification – These cable testers are the most sophisticated of the three. They cover the functions of both verification and qualification but they also can create a schematic of the entire network.


To test a modular cable plug one end to the master tester and the other end to the remote terminator (or both ends to the master unit if you are not doing a remote test). As soon as the tested cable is inserted the tester will auto-scan for continuity and mis-wiring. If the tested cable is ok the corresponding pair of LEDs will light up all green. If the corresponding pair of LEDs is lighted all RED the cable was wired reversely. If the LEDs light up green first and red after (mix) or it is unlighted the cable is bad.
