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
0.5
mA
(S00
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
2 V
AC
range
are
suitable. (See Fig. A)
