High Accuracy High Voltage Megger Portable Insulation Resistance Measuring Instrument

This instrument is designed for measuring the resistance values ​​of various insulating materials, as well as the insulation resistance of transformers, motors, cables, and other electrical equipment. Additionally, it features a step-voltage adjustment function, enabling it to output multiple distinct voltage levels (for instance, the 15kV model can generate a 12kV output, thereby offering a wider range of application).

• ★ Includes protection functions for short circuits, overloads, low battery voltage, etc.
• ★ Supports Insulation Testing, Absorption Ratio, Polarization Index, and Quick Test modes.
• ★ Displays residual voltage upon completion of testing.
• ★ The instrument automatically powers off after 10 minutes of inactivity.

• ☆ Measurement Range: 0–500 / 1000 / 2000 GΩ
• ☆ Accuracy: ±5 / 20 / 30% rdg ±5% dgt
• ☆ Operating Voltage: AC 140–240V / 50Hz; DC 16.8V
