A multifunctional tester (also called megohmmeter) with 6 voltage levels (100V~15kV). It measures insulation resistance, AC/DC voltage, current and capacitance, featuring large LCD backlight, data storage, automatic discharge and USB data upload.

1. Wide measurement range: 0.01MΩ~50TΩ insulation resistance, covering multiple electrical equipment testing needs.
2. Multiple output voltages with step adjustment, e.g., 15kV model can generate 12kV for broader applicability.
3. Integrates absorption ratio and polarization index measurement for comprehensive insulation performance evaluation.
4. IP54 protection grade, shock/dust/moisture resistant, adaptable to harsh working conditions.
5. Large LCD backlight display, 500-group data storage, USB communication for data upload and printing.
6. Automatic discharge, low battery reminder and 15-minute auto-shutdown for safe and energy-saving use.
7. High accuracy, strong anti-interference ability and stable performance, with output short-circuit current ≥6mA.
