Key Features：
Wide Output Voltage & Comprehensive Test Functions
Multiple models available with output voltages ranging from 250 V to 10 kV. It automatically measures insulation resistance, Dielectric Absorption Ratio (DAR) and Polarization Index (PI) to meet preventive test requirements for high‑voltage equipment in substations and power plants.
Multi‑layer Safety Protection & Automatic Discharge
Features automatic rapid discharge after testing, together with multi‑protection against short circuit, overload, overcurrent and undervoltage. Audible and visual alarm and automatic 10‑minute discharge function to mitigate potential safety hazards.
Built‑in Battery & Convenient Field Portability
Built‑in lithium battery, Portable and easy to operate. Compact and lightweight unit equipped with built‑in large‑capacity lithium battery. Outdoor testing can be carried out without mains power supply, suitable for field inspection tasks.
Strong Environmental Adaptability & Stable Accuracy
Low voltage measurement error ensures reliable test data. Stable operation is guaranteed at -10 ℃~40 ℃ and altitude up to 3000 m, adapting to diverse complex outdoor conditions.
