Cable Fault Locator
The 573DL is a portable instrument that measures and pinpoints sheath and conductor faults in buried or aerial cables and can also locate the path of buried cables. Four frequencies are available to accommodate varying factors such as distance, cable type, or soil conditions. A separate Tone function provides a powerful 577.5 Hz signal for identification. The instrument is also able to detect 6() Hz AC power signals. In depth measurement mode, the 573DL provides a direct digital readout of the estimated depth of buried cables, and a bar graph indication of the relative current in the cable.
