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
0.5
mA
(500
microamperes).
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
instruments.
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
voltmeter.
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
VOMs
that
are
suitable.
Nearly
all
battery
operated
digital
multimeters
that
have
a
2
V
AC
range
are
suitable.
(See
Fig.
A)
After
correcting
the
original
service
problem,
perform
the
following
safety
checks
before
releasing
the
set
to
the
customer:
1
.
Check
the
area
of
your
repair
for
unsoldered
or
poorly-soldered
connections.
Check
the
entire
board
surface
for
solder
splashes
and
bridges.
2.
Check
the
interboard
wiring
to
ensure
that
no
wires
are
"pinched"
or
contact
high-wattage
resistors.
3
.
Check
that
all
control
knobs,
shields,
covers,
ground
straps,
and
mounting
hardware
have
been
replaced.
Be
absolutely
certain
that
you
have
replaced
all
the
insulators.
4.
Look
for
unauthorized
replacement
parts,
particularly
transistors,
that
were
installed
during
a
previous
repair.
Point
them
out
to
the
customer
and
recommend
their
replacement.
5
.
Look
for
parts
which,
though
functioning,
show
obvious
signs
of
deterioration.
Point
them
out
to
the
customer
and
recommend
their
replacement.
6
.
Check
the
line
cords
for
cracks
and
abrasion.
Recommend
the
replacement
of
any
such
line
cord
to
the
customer.
7.
Check
the
B+
and
HV
to
see
if
they
are
specified
values.
Make
sure
your
instruments
are
accurate;
be
suspicious
of
your
HV
meter
if
sets
always
have
low
HV.
8.
Check
the
antenna
terminals,
metal
trim,
"metallized"
knobs,
screws,
and
all
other
exposed
metal
parts
for
AC
Leakage.
Check
leakage
as
described
right.
