The set is designed to enable the measurement of all parameters necessary for the installation of the network. The set includes a main unit, a receiver with a probe-finder and a terminator. We can detect incorrect connections, short circuits and interruptions. Using the probe, we can search the wire in the bundle to which we connected the transmitter through the proximity of the probe without the need to connect the tester. By observing the signaling of connections, we can read their map.

Cable tester - the most important features

  • detection of faulty connections, short circuits and interruptions
  • probe-finder to search for a wire in a bundle by zooming in on the probe, searching for a break
  • connection map - by observing the signaling of the connection sequence, you can read the connection map,
  • automatic shutdown
  • tests the following cables: UTP, STP, coaxial, telephone, electric
  • flashlight built into the probe
