Product information

Description

The Voltcraft CT-20TDR for shielded and unshielded cables is a handheld cable tester intended for quick verification of cable continuity and wiring integrity. It supports testing of twisted-pair and coaxial cable types used in network and communication installations, enabling technicians to locate open circuits, short circuits and wiring faults. The compact design and clear indications make the tester suitable for field use during installation, maintenance and troubleshooting tasks.

Advantages

The device offers fast detection of continuity faults and incorrect pairings, with clear LED or display indicators to streamline diagnostics on both shielded and unshielded cables. Its portable construction and simple user interface reduce the time needed for on-site checks and allow a single technician to perform routine verification without complex setup. The tool is compatible with common cabling types used in structured network installations and supports rapid verification of connection integrity to minimize downtime.

Suitable for

  • Installation and verification of twisted-pair network cabling (shielded and unshielded)
  • Maintenance and troubleshooting of communication and data cables
  • On-site fault finding for open, shorted or crossed pairs
  • Quick checks of coaxial and other common cable types used in equipment connections

Key specifications

  • Test functions: continuity and wiring integrity for shielded and unshielded cables
  • Supported cable types: twisted-pair (e.g., Ethernet) and common coaxial cables
  • Indication: visual status indicators for open, short, correct pairing and miswiring
  • Form factor: handheld, portable tester suitable for field use
  • Power: battery-powered operation for on-site testing

How to use

Connect the tester leads or modular connectors to the two ends of the cable under test, ensuring a secure connection to both conductor pairs or shielding where applicable. Power on the unit and select the appropriate test mode if required; observe the visual indicators to determine continuity, short circuits, or incorrect pair wiring. For remote segment testing, attach the remote module to the far end of the cable and run the test from the main unit. Interpret the indicator pattern according to the supplied quick reference to identify the fault location and type.

Usage recommendations

Use the tester in dry, non-corrosive environments and replace batteries before extended measurement sessions. Verify connections at both ends before testing and avoid exposing the instrument to excessive mechanical shock or moisture. For ambiguous readings, recheck connections and repeat the test; consult cable installation standards for correct pair assignments when resolving miswiring.
