clear and stable view of the signal. Set the oscilloscope input to DC volts ti
see both the AC and DC current;
Set the channel to AC to see the AC current only. 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. Figure 3 shows the difference between the line current drawn by a
resistive load and a motor controller.

Congratulations on your purchase of CP4000 series, a multifunctional current probe.
When connecting to a digital meter, use the recommended MT-246N ( BNC to banana
adapter ). Connect the black lead to the meter COM, and
the red lead to the VΩ
input .To measure only AC current, set the meter to measure AC volts. To measure
DC current, set the meter to measure DC volts. Note the current convention arrow on
the probe to get the proper polarity reading. To increase the measurement sensitivity
of CP4000, loop sensitivity of CP4000 is multiplied times the number of loops in the
jaws. For example: 10mV/A * 4 turns=40mV/A
