SAFETY
CHECK-OUT
(US
Model)
After
correcting
the
original
service
problem,
perform
the
following
safety
check
before
releasing
the
set
to
the
customer:
Check
the
antenna
terminals,
metal
trim,
‘‘metallized”’
knobs,
screws,
and
all
other
exposed
metal
parts
for
AC
leakage.
Check
leakage
as
described
below.
LEAKAGE
TEST
The
AC
leakage
from
any
exposed
metal
part
to
earth
ground
and
from
all
exposed
metal
parts
to
any
exposed
metal
part
having
a
return
to
chassis,
must
not
exceed
0.5mA
(500
microampers).
Leakage
current
can
be
measured
by
any
one
of
three
methods.
1.
A
commercial
leakage
tester,
such
as
the
Simpson
229
or
RCA
WT-540A.
Follow
the
manufacturers’
instructions
to
use
these
instru-
ments.
2.
<A
battery-operated
AC
milliammeter.
The
Data
Precision
245
digital
multimeter
is
suitable
for
this
job.
3.
Measuring
the
voltage
drop
across
a
resistor
by
means
of
a
VOM
or
battery-operated
AC
volt-
meter.
The
“limit”
indication
is
0.75
V,
so
analog
meters
must
have
an
accurate
low-
voltage
scale.
The
Simpson
250
and
Sanwa
SH-63Trd
are
examples
of
a
passive
VOM
that
is
suitable.
Nearly
all
battery
operated
digital
multimeters
that
have
a
2V
AC
range
are
suitable.
