Digifl ex Com is a compact, effi cient refl ectometer for detecting faults and measuring lengths of metallic telecommunications and power cables. Many helpful functions permit precise measuring results even in the near range <5 m and for live low voltage cables. These include e.g. resolution of 2.5 cm and a terminating set for near-range measurements, distance-dependent compensation of cable ttenuation for measure-ments up to 30 km and voltage-resistant measuring inputs up to 250V. The clearly structured LCD display ermanently shows all settings, thus eliminating any confusing menu struc-tures. Both inexperienced users and experts quickly fi nd the right settings and the required results.
A refl ectometer like the Digifl ex Com transmits short electrical pulses of just a few volts and a pulsewidth of nano to micro seconds between two connected metallic conductors. Each change in impedance causes partial refl ection of the pulse back to the device. The refl ctometer calculates the distance using the time between transmitted pulse and refl ection: the distance appears as a trace on the display. This can be used to identify cable ends, short circuits, interrupts, joints and cross-talk; distances can be read off easily.
