The probe has a zero adjustment that should be adjusted before measure-

ment. Alternatively, you may "zero" with the oscilloscope instead.

4.2

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 oscil-

loscope.

• 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.

(Remember to unclamp the probe from the conductor before discon-

necting 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).

NOTE: It is possible to change the range on the current probe without remov-

ing 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.
