The XHDD503C+ employs synchronous acoustic-magnetic localization technology—combining a high-sensitivity, fully digital probe with intelligent signal processing algorithms—to achieve precise localization of fault points, making it suitable for operation in a wide variety of complex working environments. The XHDD503C+ Cable Fault Pinpointer is suitable for use with: Power cables, coaxial cables, low-voltage cables, and electrical wires Low-resistance faults, short circuits, open circuits, and broken conductors High-resistance faults (both leakage-type and flashover-type) Emergency fault repair for urban power distribution network cables Fault pinpointing during inspections of high-voltage transmission cables Open-circuit and short-circuit detection for low-voltage cables in industrial and mining enterprises Fault localization for coaxial cables in rail transit and telecommunications systems Technical Specifications Positioning Accuracy: ≤ 0.1 m Path Accuracy: ≤ 0.5 m Detection Time Range: 0.00 – 99.99 ms Audio Gain: 16 levels (0 – 112 dB) Output Impedance: 350 Ω Acoustic/Magnetic Channel Adjustment: 8 adjustable levels each Trigger Threshold: 0 – 99 adjustable levels Filtering Mode: 5th-order superimposed filtering All-pass: 100 Hz – 1600 Hz Band-pass: 200 Hz – 600 Hz Low-pass: 100 Hz – 300 Hz High-pass: 160 Hz – 1600 Hz Noise Reduction Technology: BNR Background Noise Reduction + Mute Noise Reduction Key Features Automatic calculation of acoustic-magnetic time differences eliminates the need for manual estimation. Gain and trigger threshold settings support both automatic and manual modes. Multiple filtering options are available to adapt to varying on-site noise environments. Path deviation alerts and proximity indicators for fault points simplify operation and reduce difficulty. Background noise reduction and mute-mode noise suppression enhance the discernibility of weak signals. Portable design: the main unit weighs less than 1 kg, enabling a single operator to complete the entire workflow independently. Features a highly sensitive, noise-resistant, fully digital fixed-point probe.
