Features:
- Capacitive divider,With high precision,convenient operation and easy to move with wheels.
- The high voltage arm of one voltage divider is composed of multiple stacks of high voltage capacitors,and the other high voltage arm has only one capacitor.
- A high voltage oil paper capacitor is assembled by multiple elements in series and parallel,each element not only has a capacitor,but also a series of inherent inductance and contact resistance,and parallel insulation resistance,of course,each element has a stray capacitance.
- The high accuracy voltage meter can display DC,AC RMS(RMS),AC peak(PEAK)and peak/√2.
- Voltage meter is with strong anti-interference capability,it can customize the functions according to the client’s requirements.
