HIOKI 3273-50 Clamp on Probe
• 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.
