AC/DC Current Probe
Model SL261
The Model SL261 is designed for AC/DC
current measurement capabilities using
Hall effect technology. It measures
from a few mA to over 100A.
The “screw driver” shape, with its
narrow elongated prod, was chosen
to permit probing in crowded cable
bundles, or measuring in tight areas
such as on circuit boards, motor
controllers and automotive circuitry.
The electronics and batteries are selfcontained in the handles. It is an
excellent companion to DMMs,
recorders and loggers, oscilloscopes
and waveform displaying instruments.
Low phase shift also insures reliable
power and power quality measurements.
The Model SL261 is designed for
current measuring and displaying on
oscilloscopes. AC + DC output signals
proportional to the total current are
provided for True RMS measurements.
