1. Four voltage output selections: 500V, 1000V, 2500V, 5000V
2. Wide resistance measurement range: 0 to 200GΩ, with automatic range switching
3. High-voltage short-circuit current greater than 3mA,
4. Insulation resistance value displayed synchronously in two ways. The mechanical pointer uses an ultra-thin taut-band suspension structure with strong vibration resistance. The mechanical pointer allows easy observation of the change range of insulation resistance, while the dot-matrix LCD guides user operation and provides precise measurement results
5. The mechanical meter and LCD screen are combined into one. Dual-scale display with automatic range switching. Color-coded scale for easy reading, with corresponding LED color indication
6. Uses embedded industrial microcontroller and real-time operating software system. High automation, strong anti-interference capability. The intelligent dual-display insulation resistance tester automatically calculates absorption ratio and polarization index without manual intervention
7. User-friendly interface, with power-off protection for all measurement results, capable of continuously storing up to 20 measurement results
8. When the intelligent dual-display insulation resistance tester generates high voltage, an audible prompt is output
9. Built-in residual high-voltage discharge circuit, automatically discharges residual high voltage from the tested device after testing
10. Dual AC/DC power supply, equipped with rechargeable battery and AC adapter
