instrument,
check
that
the
line voltage
selector
switch
and
the
indicating
tab
on
the
Regulating Range
Selector
assembly
are
in
the
correct
position
for
the
desired
nominal

The
465
is
designed
to
be used
with
a three-wire AC
power
system.
If
a
three-to
two-wire
adapter
is
used
to
connect
this
instrument
to
a
two-wire
AC
power
system,
be
sure
to
connect
the
ground
lead
of
the
adapter
to
earth
(ground).
Failure
to
complete
the
ground
system
may
allow
the
chassis
of
this
instrument
to
be elevated above
ground
potential
and
pose a
shock
hazard.
The
feet
on
the
rear panel
provide
a
convenient
cord
wrap
to
store
the
power
cord
when
not
