CLAMP ON PROBE 3276

High S/N characteristics enable the measurement of
10 mA order current waveforms
Wideband Current Probe for Oscilloscopes

Hioki wide frequency current probes are best-in-class current sensors
for use with Memory HiCorders and high performance oscilloscopes. The
3276 offers a wide DC to 100 MHz bandwidth and 30A of continuous input,
and is ideal for capturing transient current signals from switching
power supplies, inverters, and motor controllers.

Model No. (Order Code)

3276	DC to 100 MHz, 30 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.

Key Features

• Waveform observation across a wide band from DC to MHz
• Connects directly to oscilloscope or Memory HiCorder BNC input terminal *1
• High S/N characteristics enable the measurement of 10 mA order current waveforms (3273-50, 3276)

*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.
