First, touch for
at least 3 seconds
the detector element pole to one of the
conductors of the first circuit. While maintaining this contact, successively
touch the auxiliary element pole to each of the conductors of the second
circuit. The conductor, which is at the same phase as the conductor being
touched on the first circuit is identified by having no pointer response on
the meter, while in the case of the two other phases the meter responds
with the phase-to-phase voltage. Use this same procedure on the other
conductors to identify them by pairs.
