SAFETY CHECK-OUT
After
correcting
the
original
service
problem,
perform
the
following
safety
check
before
releasing
the
set
to
the
customer:
Check
the
antenma
terminals,
metal
trim,
“metallized”
knobs,
screws,
and
all
other
exposed
metal
parts
for
AC
leakage.
Check
leakage
as
described
below.
LEAKAGE TEST
vow e
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
0.75V,
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
- RNING!!
suitable.
