power lines). Such strong electrical circuits may contain a surge voltage,
which is several times stronger than that of circuit voltage, thus creating a
very dangerous situation.
· Do not touch the I/O terminals during the measurement of voltage because a
high voltage may be generated on the measurement leads.
