The manual explains features, technical parameters, composition, testing methods, waveform analysis and fault locating for the HZC-III cable fault tester.
The HZC-III cable fault tester, produced by Hezhong Electric, is a high‑technology instrument that uses advanced computer technology and expert software to acquire and process high‑speed data for accurate cable fault detection. It supports multiple test methods such as DC high‑voltage flash, impulse high‑voltage sampling and low‑voltage pulse, and can locate various fault types in power, control and communication cables.
The manual is organized into sections covering the device’s features, technical specifications, hardware composition, cable fault analysis, testing procedures, measured waveform analysis, fault inspection, and additional accessories such as the HZC‑II precise locator. Appendices provide software copying instructions, key‑function tables, and printing guidance. This manual is written in Chinese.
