considers the use of rubber gloves to be an excellent
safety practice even if the equipment is properly operated and
correctly grounded.
• When testing capacitance samples, make sure that they have
been properly discharged and that they are safe to touch.
Dielectric insulation samples should be short-circuited for at
least five times the amount of time they were energized.
