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
âĒ Waveform observation across a wide band from DC to MHz
âĒ Connects directly to oscilloscope or Memory HiCorder BNC input terminal *1
*1 Connecting the deviceâs metal BNC terminal to a Memory HiCorderâs plastic BNC terminal may damage the plastic terminal or cause it to become misshapen.
