5. Adjust the oscilloscope's channel amplitude and time base settings as
necessary to get a clear and stable signal. Set the oscilloscope input to DC volts
to see both the AC and DC currents; set the channel to AC to see the AC current
only. The current drawn by selected devices can vary. While the RMS current
can only be used in low frequency current, the transient peaks can be quite high.
Figure 3 shows the difference between a line current drawn by a resistive load
and a motor controller.
Figure 3: Typical current waveforms
When connecting the current probe to a Digital Multimeter (DMM), use the
included BNC-to-banana adapter (CT3956). Connect the black banana plug on
the adapter to the DMM's COM or ground jack and the red banana plug to the
VΩ jack.
To measure only AC current, set the meter to measure AC volts. To measure
DC current, set the meter to measure DC volts.
