3275

Wideband Current Probe for Oscilloscopes

Hioki flat bandwidth current probes are best-in-class current sensors for use with Memory HiCorders and high performance oscilloscopes. The 3275 supports wide DC to 2 MHz bandwidth signals and 500A of continuous high input, and is ideal for capturing transient current signals from switching power supplies, inverters, and motor controllers. 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)

3275 DC to 2 MHz, 500 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.
