Product Overview
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.
