CLAMP ON PROBE
3274

Wideband Current Probe for Oscilloscope
Exclusive Academic Offer

Hioki flat bandwidth current probes are best-in-class current sensors for use with Memory HiCorders and high performance oscilloscopes. The 3274 supports wide DC to 10 MHz bandwidth signals and 150A of continuous high input, letting you capture transient current signals from switching power supplies, inverters, and motor controllers. The probe is designed with a high permeability magnetic shield to reduce the effects of electric fields, making it ideal for measuring low currents or nearby high-current lines.

Key Features
• Waveform observation across a wide band from DC to MHz
• Connects directly to oscilloscope or Memory HiCorder BNC input terminal *1

*1 Connecting the device’s metal BNC terminal to a Memory HiCorder’s plastic BNC terminal may damage the plastic terminal or cause it to become misshapen.

Model No. (Order Code)

3274 DC to 10 MHz, 150 Arms

Note: Use the Power Supply 3269/3272 for general measurements or when power is not available from the Memory Hicorder. When performing continuous measurements, be aware of offset voltage drift.
