General
TDR measurement range	700 m

The cable measurement device PS_CT 50 from Softing IT Networks is a multifunctional device for diagnosing and locating copper cables. It is used to determine cable length as well as the distance to faults such as cable crushes, breaks, or short circuits. The device is suitable for various cable types, including network and telephone cables, coaxial cables, and conventional power supply cables. The core function is based on an integrated Time Domain Reflectometer (TDR), which precisely measures the length of the lines. Additionally, the device features a voltmeter function that detects voltages up to 250 V to identify live lines. An integrated tone generator enables cable tracing, with tracing in cable ducts or under plaster possible using an optional CableTracker probe.

Applications

The PS_CT 50 is used in the field of electrical and IT installation, particularly for fault finding in cable networks. It is suitable for testing data cables, telephone lines, antenna cables, and power cables. The TDR function enables the localization of damage along the cable route, making the search for breaks or short circuits more efficient. The voltmeter function helps identify live lines to avoid unintended contact. Cable tracing with the tone generator is useful for identifying cables in complex installations, especially in combination with the optional CableTracker probe.

Functions and Equipment in Detail

The device measures cable length or the distance to a fault using the TDR method. The maximum measurement range is 700 meters. The voltmeter function detects voltages up to 250 volts to identify live lines. The integrated tone generator produces an acoustic signal that is transmitted through the cable and can be detected with a receiver. Cable tracing is particularly helpful when cables are installed in wall runs or cable ducts. Optional accessories such as the CableTracker probe extend functionality for precise tracing in confined spaces.

Technology Explained Simply

A Time Domain Reflectometer (TDR) sends a short electrical signal into the cable and measures the time until a reflection returns. From this time, the length of the cable or the distance to a fault is calculated. This method is especially useful for locating breaks, short circuits, or crushes in the cable. The voltmeter function detects whether a line is energized, which is important when working on electrical installations to prevent accidents. The tone generator produces a signal that is transmitted through the cable and can be detected with a receiver, facilitating cable identification in complex installations.

Compatibility and Accessories

The PS_CT 50 is suitable for all common copper cable types, including network, telephone, coaxial, and power supply cables. The integrated functionality includes length measurement, voltage detection, and cable tracing. For extended tracing tasks, the optionally available CableTracker probe can be used to clearly locate the cable path in cable ducts or under plaster. The use of alligator clips and coax adapters (BNC and F-type) enables flexible connection to various cable types.

Mounting and Installation

The device is directly connected to the cable to be tested, using alligator clips or coax adapters depending on the cable type. Measurement is performed without additional mounting or installation. Operation is carried out via the device's controls, which activate the various functions (length measurement, voltmeter, tone generator). Results are displayed directly on the screen.

Advantages in Operation

The PS_CT 50 combines multiple functions in one device, increasing efficiency during fault finding. The TDR function enables precise localization of faults, accelerating the search for damage along the cable route. The voltmeter function increases safety by detecting live lines. Cable tracing with the tone generator and optional probe simplifies cable identification in complex installations. The device is suitable for various cable types, increasing its applicability across different industries.
