DIFFERENTIAL PROBE 9322

3 Kinds of Measurements with a Single Probe

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

Key Features

  • Floating measurement of high-voltage waveforms (DC mode)
  • Detection of power supply surge noise (AC mode)
  • RMS rectified output (RMS mode)

Main Applications

  • Measure potential differences included in common mode voltages, such as IGBT
  • Measure commercial power line waveforms, such as on 400V power lines
  • Measure high voltage surge noise waveforms
  • Measure the RMS value of inverter output, etc.
