5 Measurements

This section describes basic performance of measurements with the METRACABLE TDR PRO. Detailed information, as well as information concerning additional functions and other measurements (e.g. for coaxial cables), can be found in the operating instructions (available at http://www.gossenmetrawatt.com).
The METRACABLE TDR PRO is connected to the voltage-free cable to be measured. It performs a TDR measurement (time domain reflectometry) whose results appear at the display as a TDR trace.
The instrument transmits an electrical pulse during measurement. Cable length can be calculated based on the amount of time it takes for the pulse signal to be returned to the instrument (reflection). The shape of the reflection provides information concerning:
· Any included components (e.g. a splitter)
· The wiring itself (e.g. splices, branches etc.)
· Cable faults (short-circuits, broken cable, pinching etc.)
The locations of these items are also calculated accurate to approximately 0.3 m based on the time it takes for the signal to return to the instrument.
Cables with lengths of up to 14 km can be examined with the METRACABLE TDR PRO.
Proceed as follows:
1. Perform measurement 20. 2. Evaluate the reflection “Typical Reflection Curves and
Their Meanings” 24. 3. View the information at a PC for detailed observation and
evaluation “METRACABLE MANAGER Software” 25.
