Because current measurement requires the insertion of a shunt or a CT, the task often becomes difficult due to breaks in the electrical path. The Hioki 3273-50 50MHz 30A AC/DC Current Probe only need to be connected directly into the BNC input on waveform observation equipment such as an oscilloscope or a recorder. Then simply clamp onto the Hioki 327350's conductor to be measured to easily observe current waveforms under a wide bandwidth and high sensitivity conditions.
