Netwerkkabeltester Voltcraft CT-1 voor BNC en RJ-45, test 10Base-T UTP/STP

Voltcraft CT-1 is a handheld network cable tester designed to check continuity and wiring integrity for BNC coaxial connectors and RJ-45 Ethernet plugs. Compatible with 10Base-T UTP and STP cabling, the tester verifies pin-to-pin connections and identifies open circuits and short circuits across a cable run. The compact, portable unit is intended for installation and maintenance tasks where quick verification of link wiring helps reduce troubleshooting time and prevent connection issues.

Advantages

The tester provides straightforward verification of both BNC and RJ-45 terminations without requiring complex setup, enabling fast detection of wiring faults. Its simple interface and visual indicators make it easy to interpret results on-site. The device is battery-powered and lightweight, facilitating transport between job sites and access to confined spaces where cables are installed.

Suitable for

• Installation and commissioning of 10Base-T Ethernet networks using UTP or STP cable
• Field diagnostics of coaxial BNC connections in CCTV or legacy networks
• Maintenance checks and verification after cable repairs or re-terminations
• Quick on-site continuity checks during network upgrades or moves

Key specifications

• Connector support: BNC and 8P8C (RJ-45) connectors
• Cable types: compatible with unshielded twisted pair (UTP) and shielded twisted pair (STP) and coaxial
• Function: continuity testing, wiring integrity check, open/short detection
• Power supply: battery-operated for portable use
• Display/indicators: visual LED indication for individual conductor status
• Form factor: compact, handheld design suitable for field use

How to use

Connect one end of the cable to the main unit and the other end to the remote or secondary connector as applicable (BNC to BNC or RJ-45 to RJ-45). Switch the tester on and observe the indicator sequence or LEDs that correspond to each conductor. A continuous sequence indicates correct wiring and continuity; interrupted or missing indications reveal open circuits, while simultaneous indications on multiple conductors can signify short circuits. Replace the battery if indicators are weak or do not light up. Follow standard safety practices by disconnecting live network equipment before testing.

Recommendations

Use the Voltcraft CT-1 to verify wiring before powering or connecting network devices, and perform tests after any termination, repair, or cable routing changes. Store the tester in a dry environment and replace batteries periodically to ensure reliable performance during installation and maintenance tasks.
