SAFETY
CHECK.OUT
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
gtound
and
from
all exposed
metal
parts
to any
exposed
metal
part
having a return to
chassis,
must
not exceed
0.5 mA
(500
microampers).
Leakage
current
can be measured
bv anv one of three
methods.
I
.
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
2
V AC
range are
suitable.
