Probing Principles
Measuring Differential Current
To simplify your differential or n ull current
measurements, you can place two conductors
in one current probe.
WARNING. Do not put uninsulated conductors in the probe. An uninsulated conductor is any conductor without insulat ion or
without insulation rated for the voltage prese nt on the conductor under test.
An insulated conductor is any conductor that is surrounded by an insulating material that is capa ble of isolating the voltage prese nt
on the cond uctor. Lacquer coatings like those typically found on transformer windings do not provide sufficient, reliable insulation
for use with current probes. The lacquer coating can be easily nicked or damaged, compromising the insulating ca pabilities of
the lacquer coating.
Do not force the slide closed. Damage to the probe may result. If you cannot close the slide around the condu ctor(s), either reduce
the n umber of conductors you are measuring, or, if possible, take yo ur measurement on a smaller conductor.
