In this field demonstration, we showcase the XHDD503B HV Cable Fault Pinpointer in action, showing how its synchronous acoustic-magnetic technology precisely locates underground cable faults. You'll see the step-by-step process of using the 5-inch touchscreen interface, adjusting signal gains for different environments, and interpreting the real-time waveform display to achieve 0.1m accuracy. Watch as we demonstrate how the time difference between acoustic and magnetic signals leads directly to the fault location, making field operations more reliable than traditional acoustic-only methods.
