A cable tester is an electronic device that simply measures the conductive between two ends of a cable. It also checks and measures signal for correct wiring. There are two most common ways of testing the connection:

  • Tester sends a current down the wire and measures its level. This is called a continuity testing.
  • Tester sends a current and a voltage down the connection. Then by measuring a voltage and current, it calculates a resistance. This is called resistance testing.

What's a typical application of Network Cable Testers?

Due to different types of data that can be transmitted over the Ethernet network data cables. Testers are suitable for testing computer Cat 3, Cat5, Cat5e, Cat6, Cat6a, Cat6e, Cat 7 cables.
