p. If you do not know how the equipment works and what
the hazards associated with the equipment are in specific
terms, do NOT handle the equipment. The greatest
protection you can have when dealing with high voltage
equipment is specific, detailed knowledge on that particular
piece of equipment.
q. Avoid "haywire" test setups. It is easy to get in trouble if
the setup you are using has a jumble of wires.
r. Make sure your connections are secure. Do NOT allow
leads to slip off and move about in an uncontrolled fashion.
Even if it is not one of the high voltage leads, a free lead
could (and generally does) move exactly to where you do
not want it. The only safe connection is a mechanically
secure one.
s. Watch out for unterminated high voltage leads. Some
connectors depend on circuit loading to avoid arcing
between closely spaced terminals. Unloaded high voltage
lines or plugs can lead to arcing situations.
t. Shut off the high voltage when you are making low
voltage measurements. It does not make sense to increase
danger needlessly. While there may be times when you
cannot shut off the high voltage during a low voltage
measurement, this is generally not the case.
u. Remove the test equipment when you have finished a
measurement program. There have been many instruments
destroyed or damaged because a test program was
conducted in a haphazard manner, rather than in an orderly
progression from start to finish. Experience has shown in
many instances when a little order would have prevented a
tragedy or avoided an expensive mistake.
v. Be extremely wary when making filament voltage
measurements. The cathode of tubes is elevated above (or
below) ground and the filament voltages usually cannot be
measured with reference to ground. Do everything you can
to assure that the high voltage cannot be turned on when
you are making your measurements. This includes
