Probing Principles
1. Orient the two conductors un der test so
that the polarities (+ and –) o ppose each
other.
2. Clamp the current probe around the two
conductors. Be careful not to pinch a
conductor in the probe jaws.
3. Measure the current.
Conventional current flows from positive to
negative. A wavefo rm ab ove the baseline
indicates that the conductor with the
conventional current flow in the direction
of the probe arrow is carrying the greate r
current.
