3.Plug in the other end of the test lead into a multimeter. It is strongly
recommended a TRUE RMS multimeter is used for AC current
measurement for more accurate reading.
4.Make sure current probe's and multimeter's COM terminals are connected.
5.Set the range of multimeter at 200 or 400 mVAC for AC current
measurement.
6.Press the trigger to open the jaw and fully enclose the conductor to be
measured. No air gap is allowed between the two half jaws.
7. Read the measured value from the meter's display.
C. Current Waveform Observation (Connected to an Oscilloscope)
1. Find a BNC converter which converts the test plugs into BNC connector.
2. Set the rotary switch at 4A, 40A or 200A.
3. Connect the test plugs into current probe's terminals.
4. Connect the other ends of test leads into BNC converter.
5. Connect the BNC converter into oscilloscope's input.
6. Make sure the polarities of current probe and oscilloscope are connected
correctly.
7.Press the trigger to open the jaw and fully enclose the conductor to be
measured. No air gap is allowed between the two half jaws.
8. Select appropriate voltage range(eg. mv/div) so that output (200mV or 400mV
full scale) from current probe can be observed from oscilloscope.
