  • 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. Resistance testing is measuring a voltage and current, it calculates a resistance.


What is a typical application of Network Cable Testers?


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