Current Probe | CLAMP ON PROBE 3276

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. 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.

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.
