• Dual operation modes: Automatic (with APP control) and manual modes for flexible testing.
• 7-inch touchscreen display: Clear visualization of voltage, current, time, and status data (optional 10-inch).
• Full Chinese interface: Intuitive operation with status reminders for safe use.
• Digital calibration: Replaces traditional potentiometer adjustment for precise control (password-protected).
• Intelligent voltage control: Gradually reduces ramp speed as voltage approaches target (80% → 90% → 100%).
• Automatic timing & result judgment: Triggers audible alarms for pass/fail outcomes.
• Pause function: Allows mid-test voltage hold for sample observation (auto mode only).
• Anti-interference design: Combines hardware and software filtering for stable performance.
• Safety alerts: Flashing high-voltage indicator and audible warnings during testing.
• Compliance: Meets IEC 60270, IEC 60464, GB/T 16927, and ASTM D149 standards.
