Our team walks you through how the XZH TEST XHDD503C Time Domain Reflectometer performs in common cable fault scenarios. In this video, you'll see a complete demonstration of locating underground cable faults using advanced signal reflection analysis. We'll show you how to operate the 5-inch high-brightness touch LCD interface, calibrate wave velocity for different cable types, and interpret waveforms to pinpoint breaks, shorts, and water intrusion spots with precision.
