Auto test ability makes the detection much easier. Bi-polar pulse reduces attenuation and distortion of reflection. While the auto test ability makes the fault detection a much easier job, the manual operation interface provides an experienced operator more test flexibilities. Bi-polar pulse reduces attenuation and distortion of reflection of long distance fault, which significantly makes fault reflection to be recognized easier and increases accuracy. Comprehensive operation modes enable close up faults within few meters, to be located without the need to use interposing delay lines or coils of cable.Pulse velocity can be calibrated to any cable dielectric.While mainly designed for telephone cable with 8 Km range it can be easily modified to test longer distance cable.Using internal rechargeable li-ion battery with power save mode and power low indication, the instrument can continuously work for 5 hours without recharging. Up to 10 waveforms can be stored in internal no-volatile memory for later analysis, or computer read out through USB Disk, this make the waveform no limitation storage.A PC software package provides powerful fault reflection traces analysis capability. The fault point can be discriminated even easier by comparing a fault cable reflection with the trace recorded when the cable was “good”.A big LCD screen (320*240) with backlit gives much clearer waveform and message display.Immune to the effect if induced or impressed voltages on the cable under test.Portable and rugged design makes the unit easy to carry and withstand tough field environment.
