The CZ1000 Cable Pair Identifier (F-Set) is the original and best cable tracer and pair identifier used by electricians, telecommunications, and data cabling companies Australia wide. Designed for finding conductors in multi pair cabling applications, particularly in copper telecommunication cables, it soon became the standard tone and probe for telecommunications. Once electricians realised how good it was as a cable tracing tool it soon became the standard cable tracing tool for the electrical industry. Electricians, technicians, engineers, and tradespeople all rely on the CZ1000 to get their daily jobs done. The CZ1000 was a world first when developed, and has now been the industry standard for more than 25 years. Designed by Australian manufacturer Aegis, the CZ1000 is suitable for and compatible with copper cable networks and systems worldwide. It is the market leader with a strong heritage and proven quality, beating out its competitors in terms of value for money, time and time again. There are many tone and probe products on the market but none can match the CZ1000! Applications of the CZ1000 (F-Set) include:

  • Cable pair ID in data and telecommunications cables
  • Cable tracing
  • Short circuit identification
  • Polarity identification on telecommunications cable
  • Cable identification and tracing in data networks (Cat 5, Cat 6, Cat 7, etc)
  • All tone and probe applications


The simplicity of the CZ1000 is a major component of its longstanding success.

The set comprises of two main items, a transmitter and search probe. The transmitter is co ected to the cable to be traced via either crocodile clips or a RJ11 plug. This co ection provides the tracing signal which the probe can then detect. The probe is activated by a push button switch. A warble tone will be heard when the tip of the probe is over the wanted cable or pair. The new tone on short feature gives confirmation of the identified pair by triggering an audible buzzer at the transmitter when the pair is shorted together. Not to be overlooked is the carry case supplied with the CZ1000.The durable, hard carry case integrates the operator manual and makes for easy storage and transport, protecting your CZ1000 from damage at all times. The CZ1000 is suitable for data, electrical, and telecommunications cables and enables co ection to the most common terminations with ease. The CZ1000 has a long service life and uses standard batteries available from most retail outlets. It is already the preferred Cable Pair Identifier for the Australian telecommunications industry, the preferred cable tracer for the Australian electrical industry, and the preferred tool for Australian networking technicians. It has gained a reputation as the best tool in the market based on its high quality, ease of use, and numerous applications. Features of the CZ1000 (F-Set) include:

  • An easy to use system with single button operation
  • 240V mains protected transmitter
  • continuity buzzer (tone on short)
  • Line polarity indication for use on live telecommunications networks
  • A modular plug / clip lead set (RJ11 and crocodile clips)
  • Compatibility with networks worldwide
  • Hard carry case as standard
  • A proven tone and probe combination
  • A quality design, refined and proven over 25 years

Aegis has celebrated over 80 years of servicing the communications industry.
Aegis has designed, manufactured and supplied Australian industry with test equipment for more than 80 years. Over the past 8 decades we have expanded to become one of the most diverse and trusted manufacturing companies both nationally and globally.

Aegis was established in Melbourne, Australia in 1933. In those formative years we developed and manufactured assembly kits to service the needs of early radio enthusiasts. These kits included everything required to build your own radio receiver including coils, transformers, ceramics and Bakelit housings.

We’ve come a long way since then. As information and technology have developed at a remarkable pace, so to has Aegis. The rapid evolution of communications technology throughout the 20th century required us to remain at the forefront of engineering design, and by the mid 1970s the company was becoming increasingly involved in the telecommunications industry.

It was at this time that Aegis forged a close relationship with Telecom Australia (now Telstra) and undertook a number of innovative product developments such as the CZ1000 Cable Pair Identifier and the CZ3000 handheld, non-balancing digital bridge, which proved so successful that they have since been imitated by other companies throughout the world.

Our commitment to innovation in the telecommunications industry remains to this day. We now service a wide range of customers in the data, electrical, gas, telecommunications, and water industries all around the world. We strive to provide cost effective solutions designed to safely and accurately locate and test networks in all industries.

Aegis specialises in working with the industry to understand what is required and design an instrument to suit. Our experience and expertise have helped our products become industry standard and we continue to remain one of the premier test equipment suppliers.

Major utilities in the telecommunications, gas, and water industries rely upon Aegis equipment to maximise the efficiency and effectiveness of their networks. These products have evolved to become the standard tools for tradespeople Australia wide, and are successfully used in Europe, Asia and the Pacific Region. We continue to seek new markets where our expertise can help solve any problem for our customers.
