Read the warnings in
Connect the current probe to an input channel on the
oscilloscope.
Connect the probe to the oscilloscope or vol tage measuring instrument
before clamping the probe around a conductor.
Set the current probe to its least sensitive range (10 mV/A).
Select the 0.5 V/division range on the oscilloscope.
Clamp the probe on the conductor to be measured and read the
current flowing directly on your oscilloscope.
You may also use your oscilloscope to amplify the signal while
using the 100 mV/A probe range (which offers the best accuracy
and least phase shift).
It is possible to change the range on the current probe without removing
the probe from the current carrying conductor, but never exceed the
permissible peak ratings of 1000 mV peak or 2000 mV peak-to-peak
maximum. The peak ratings by range are: 10A peak on the 100 mV/A
range, 100A peak on the 10 mV/A range.
Remove the probe from any circuit under test and from the
oscilloscope.
Clean the external surfaces of the probe with a soft cloth
dampened with a mixture of mild detergent and water.
Clean the mating surfaces of the probe's jaws so that they are free
of dirt or foreign matter. If rust is present, gently clean the mating
surfaces with a soft cloth that has been lightly oiled with standard
machine oil. Do not leave excessive oil residue.
Make sure that the probe is completely dry before reconnecting it to a
power source.
