It is widely used for testing: Household Appliances (IEC 60335) Power Cables & Connectors Electric Tools (IEC 60745) Lighting Equipment (LED Drivers, Luminaires) IT/AV Equipment (IEC 62368, IEC 60950) Motors, Transformers, and PCBs

• 4-CHANNEL MATRIX SCANNING & DUAL TESTING MODES: Perform efficient high-voltage safety tests on multiple products simultaneously with the built-in 4-channel matrix scanner. This programmable hipot tester combines AC/DC Withstanding Voltage Test (up to 5kV AC/6kV DC) and Insulation Resistance Test (0.1MΩ to 10.0GΩ) in one robust instrument.
• ENHANCED SAFETY WITH ARC DETECTION & FAST DISCHARGE: Features advanced arc detection function with 1-9 adjustable levels for both AC and DC tests, preventing faulty components from passing. The automatic fast discharge function (for DCW and IR tests) ensures operator and device safety by quickly dissipating residual voltage after each test.
• FLEXIBLE PROGRAMMING & DATA STORAGE: Store up to 20 complete test files, each containing 20 test steps. Freely combine AC/DC hipot and IR tests in any sequence. Precisely control voltage ramp time (0.1-999.9s), test time, fall time, and specifically for IR test, a programmable waiting time (0.2-999.9s) for stable readings.
• HIGH PRECISION & WIDE MEASUREMENT RANGE: Delivers accurate results with ±2% voltage output accuracy and a wide current measurement range (1μA-20mA AC / 0.1μA-10mA DC). The insulation resistance test offers a broad range from 0.1MΩ to 10.0GΩ with defined accuracy for reliable pass/fail decisions.
• USER-FRIENDLY DESIGN & FUNCTIONALITY: The 4.3-inch TFT-LCD (480x272) provides a clear display of settings and results. Features include a keyboard lock function to prevent accidental changes, a simplified interface for easy operation, and the ability to upgrade the firmware via a USB drive, ensuring your device stays up-to-date.
