LEAKAGE TEST (FOR SERVICE ENGINEERS IN THE U.S.A.)
Before
returning
the
unit
to
the
user,
perform
the
following
safety
checks:
1. Inspect all lead dress to make cer-
tain that leads are not pinched or
that hardware is not lodged be-
tween the chassis and other metal
parts in the unit.
2. Be sure. that any protective devices
such as nonmetallic control knobs,
insulating fishpapers, cabinet backs,
adjustment and compartment cov-
ers or shields, isolation resistor-
capacity networks, mechanical in-
sulators, etc. which were removed
for servicing are properly reinstalled.
3. Be sure that no shock hazard exists; check for leakage
current
using
Simpson
Model
229
Leakage
Tester,
standard
equipment
item
No.
21641,
RCA
Model
WT540A
or
use
alternate
method
as
follows:
Plug
the
power
cord
directly
into
a
120-volt
AC
receptacle
(do
not
use
an
Isolation
Transformer
for
this
test).
Using
two
clip
leads,
connect
a
1500
Ohm,
10-watt
resistor
paralleled
by
a
0.15uF
capac-
itor,
in
series
with
all
exposed
metal
cabinet
parts
and
a
known
earth
ground,
such
as
a
water
pipe
or
conduit.
Use
a
VTVM
or
VOM
with
1000
Ohms
per
volt,
or
higher,
sensitivity
to
measure
the
AC
voltage
drop
across
the
resistor.
(See
Diagram.)
Move
the
resistor
connection
to
each
exposed
metal
part
having
a
return
path
to
the
chassis
(antenna,
metal,
cabinet,
screw
heads,
knobs
and
control
shafts,
escutcheon,
etc.)
and
measure
the
AC
voltage
drop
across
the
resistor.
(This
test.should
be
performed
with
the
power
switch
in
both
the
On
and
Off
positions.)

which
must
be
corrected
bef
returning the unit to the owner.
