2 2 CLAMP ON PROBE to 3276 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 CLAMP ON PROBEs 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 conductor to be measured to easily observe current waveforms under a wide bandwidth and high sensitivity conditions.
