The energy accumulated in an
inductive
component when a measurement is made on it must be released.
You must never in any circumstances touch or disconnect the measurement leads until you
have stopped making the measurement and waited at least ten seconds
for all of the energy in the
item tested to be dissipated. Failure to observe this precaution may result in the production of an arc,
potentially hazardous for both the instrument and the operator.
