Hioki Differential Probe 9322

High performance differential probe supports 3 types of measurements

The 9322 is a differential probe used to measure high voltage with Hioki Memory HiCorders.

The Differential Probe 9322 cannot be used by itself. Use with an analog input unit for Memory HiCorders. Power supply connection differs depending on the connected Memory HiCorder.

Floating measurement of high-voltage waveforms (DC mode)
• Detection of power supply surge noise (AC mode)
• RMS rectified output (RMS mode)
• Main Applications
1. Measurement of potential differences included in common mode voltages, such as IGBT
2. Measurement of commercial power line waveforms, such as on 400V power lines
3. Measurement of high voltage surge noise waveforms
4. Measurement of the RMS value of inverter outputs, etc.
