SAFETY CHECK-OUT
After correcting
the origina
l 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
touching high-wattage resistors.
3.
Check that all control knobs, shields, cove
rs, ground straps, and
mounting hardware have been replaced. Be absolutely certain that
you have replaced all
the insulators.
4.
Look for unautho
rized replacement part
s, 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 antenn
a terminals, metal trim, “metallized” knobs, screw
s,
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 (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
instructions.
2.
A
battery-oper
ated
AC milliampmet
er.
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 “li
mit” indication is
0.75
V, so analog meters must have an accurate low voltage scale.
The Simpson’s 250 and Sanwa SH-63TRD are examples of
passive VOMs that are
suitable. Nearly all battery-operated digital
multimeters that have a 2 VAC range are suitable (see Figure A).
How to Find a Good Earth Ground
A cold-w
ater pipe
is a guarant
eed earth
ground; th
e cover-plate
retaining screw on most AC outlet boxes is also at earth ground. If the
retaining screw is to be used as
your earth ground, verify that it is at
ground by measuring the resistance between it and a cold-water pipe
with an ohmmeter. The reading should be zero ohms.
If a cold-water pipe is not accessible, connect a 60- to
100-watt
trouble- light (not a neon lamp) between the hot side of the receptacle
and the retaining screw. Try both slots, if necessary, to locate the hot
side on the line; the lamp should light
at normal brilliance if the screw
is at ground potential (see Figure B).
