shock,
the
third
wire earth
ground
must
be
con-
tinuous
to the

Before connecting
to
the
facility
power
outlet,
examine
extension
cords, auto-
transformers,
etc.,
between
the
instru-
ment and
the
facility
power
outlet
for
a
continuous
earth
ground
path.
The
earth
ground
path
can be
identified at
the
plug
on
the
instrument
power
cord; of
the three terminals, the earth
ground
terminal
Is
the
nonmatching
shape,
usually
cylindrical.
CAUTION
