CLAMP SENSOR Wide-band Models from DC to 100 MHz 3276 CLAMP ON PROBE http://www.hioki.co.jp/ HIOKI company overview, new products, environmental considerations and other information are available on our website. 1 3273-50 to 3276 CLAMP ON PROBE 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 3273-50 - 3276 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.
