Operation; Zero Adjustment; Current Measurement - AEMC SL261 User Manual

4.1
The probe has a zero adjustment that should be adjusted before
measurement. Alternatively, you may "zero" with the oscilloscope instead.
4.2
(Remember to unclamp the probe from the conductor before
disconnecting it from your meter or instrument.)
You may also use your oscilloscope to amplify the signal while using the
100mV/A probe range (which offers the best accuracy and least phase
shift).

Current Measurement

WARNING: Always connect the probe to the instrument before clamping onto
the circuit under test.
• Connect the Model SL261 to the proper input channel on the
oscilloscope.
• Begin with the least sensitive range on the current probe (10mV/A).
• Select the 0.5V/Division range on the oscilloscope.
• Clamp the probe on the conductor to be measured and read the
current flowing directly on your oscilloscope.
NOTE: It is possible to change the range on the current probe without removing
the probe from the current carrying conductor, but it is important to remember
not to exceed the permissible peak ratings of 1000mV peak or 2000mV peak
to peak maximum. The peak ratings by range are: 10A peak on the 100mV/A
range, 100A peak on the 10mV/A range.
