3. Measure the current. A waveform above the baseline indicates the conductor
with the conventional current ow (I

, in the direction of the probe arrow),
is carrying the greater c urrent. Conventional current ows from positive to
negative.
4. To adjust for a current n ull, adjust the current in one of the conductors until
the displayed measurement is zero.
