Figure 3: Typical current waveforms
If you are using the A622 current probe with a multimeter, connect
the probe with the recommended BNC-to-banana ada pter. Conne ct
the black lead to the meter COM, and the red lead to the VΩ input.
To measure only AC current, set the me ter to measure AC volts.
To measure DC current, set the meter to measure DC volt s. Note the
current conventi on arrow on the probe to get the proper polarity
reading.
To increase the measurement sensitivity of the A622 current probe,
loop additional turns of the wire under test through the jaws. See
Figure 4. The sensitivity of the A622 current probe is multiplied
times the number of loops in the jaws. For e xampl e: 10 mV/A X 4
turns = 40 mV/A.
