CLAMP ON PROBE
3275

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 3275 supports wide DC to 2 MHz bandwidth signals and 500A of continuous high input. The probe is designed with an electrostatic shield to reduce the effects of electric fields, making it ideal for measuring in environments in which the probe will be subjected to the effects of nearby magnetic fields, such as locations with high-voltage switching control equipment such as an inverter or motor.

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.
