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.

Composed of molded parts, ferrite and Hall
elements. The thin-film of the Hall element
especially improves detection sensitivity to realize
wider bands and high sensitivity monitoring.
(Provided that connector type, pin assignment, voltage, and capacity rating
match, the 3273-50 to 3276 can be powered also from another source. For
operation safety, be sure to refer to the specifications to ensure an exact match.)

DC to MHz Range
A wide range of current waveforms from DC to MHz can be
observed at high precision. The 3270 is a DC/AC amplifier that can
be connected to the 9274/9276 to enable current waveforms to be
recorded and easily observed by connecting a recorder or
oscilloscope.

CURRENT MONITOR
● Incorporates our custom-developed InSb
thin-film Hall element
The high degree of electron mobility in InSb makes it ideal for
our highly sensitive thin-film Hall element. We have adapted
these qualities for measuring a wide range of current, as well
as for very low levels.

! WARNING
1. To avoid short circuits and electric shock accidents when using a clamp-on sensor, use only with power lines carrying voltages within the rating limit of the sensor.
2. To avoid short circuits and electric shock accidents when the clamp-on sensor is open, do not use on bare conductors.
