CLAMP ON PROBE 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. 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.
Use with an instrument with a high input impedance of 1 MΩ or higher.
- Waveform observation across a wide band from DC to MHz
- Connects directly to oscilloscope or Memory HiCorder BNC input terminal (*1)
- *1:Connecting the probe's metal BNC terminal to a Memory HiCorder’s plastic BNC terminal may distort or damage the plastic terminal. To avoid damage, please connect and disconnect the probe cable straight to the BNC terminal of the waveform monitoring equipment.
