5 Adjust the probe channel and oscilloscope as necessary to get
a clear and stable view of the signal. At this point, you can see
both the current components of AC and DC. Set the coupling
mode of the oscilloscope to AC to see the current components
of AC. The operation method of the current components of AC
is the ratio of the voltage amplitude measured through the
oscilloscope and the switch range currently selected of the
current probe (50 mV/A or 500 mV/A).
Note: The current drawn by different devices look much
different than that of others. While the RMS current can only
be used in low frequency current, the momentary peaks may
be quite high. The figure on the next page shows the
difference between the line current drawn by a resistive load
and a motor controller.
