The cable tester and cable finder set KE7801 is the ideal basic equipment for all technicians searching for cables and faults in telephone and data networks.

The KE7000 are easy to use test devices for patch, LAN and telecommunication cabling and coaxial cables. Unshielded and shielded connection cables with twisted pairs (UTP and STP cables) in installed networks or patch cables can be tested and verified. BNC and F-socket coaxial cables can be tested for continuity using the RJ45 coax adapter.

Occurring errors such as mix-ups, interruptions, short circuits and screen errors are shown on the displays. The KE7000 provide clear, fast and immediately evaluable status information on the LCD displays for cable lengths up to approximately 150 m.

The cable tracer kits consist of EASYTEST and PROBE and enable any technician to find any type of cable, wires and wire pairs in the shortest possible time without time-consuming skinning work. The cable finders can be used for all types of cables such as telephone cables, bell lines, data cables of all classes, coaxial cables and voltage-free electrical lines and are overvoltage protected against accidental contact with external voltage > 100 V.

The KE7801 set combines two KE7000 with the KE801 Fibre & Copper Kit. Like the K3E01 Classic Kit, it features a tone generator with a RJ11 connector, two crocodile clips and a continuity test via LED. Additionally, like the KE701 Telco Kit, it comes equipped with a RJ45 connector for detecting active network connections and assigning the active data port to e.g. the switch. A continuity test with a resistance-dependent tone enables a quick assessment of the cable condition. It is protected against accidental contact with 230 V mains voltage through an overvoltage protection up to 500 V.

On top of that, the unique KE801 Fibre & Copper Kit extends the range of functions with a red light source, which enables visual continuity testing in fibre optic networks (VFL). The coax F socket also allows tracking of coaxial cables.

KE7801 – reliable, robust and cost-effective.
