The KD-212N Cable Reel Multi-Parameter Tester is an innovative diagnostic instrument that integrates advanced image recognition technology with multi-electrical parameter measurement to deliver a comprehensive cable quality assessment solution. By combining imaging analysis, traveling wave testing, and electrical parameter diagnostics, this system provides highly accurate measurements of conductor effective cross-sectional area, long conductor length, DC resistance, unit length resistance, cable capacitance, and ambient temperature. The unique imaging method analyzes the cable end face to determine the effective cross-sectional area, offering significantly higher precision than traditional caliper-based diameter measurements for various cable types. The traveling wave measurement technique injects low-voltage pulse signals and uses high-speed counting of reflection time to accurately determine cable length through impedance mismatch analysis. The precision resistance measurement module features automatic temperature correction for consistent accuracy, while the optional capacitance measurement module provides an alternative method for length verification through capacitance comparison. The system comprises the main tester unit, a tablet computer for intuitive operation, length measurement leads, five-terminal measurement leads, and optional accessories including a dedicated imaging fixture, cable cutter, and cable standard gauge ruler. With its multi-method approach and advanced technology integration, the KD-212N sets a new standard for on-site cable quality verification and conductor inspection.
