SAFETY CHECK-OUT
{US Model only)
After correcting the original service problem, LEAKAGE TEST
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 abso lutely certain that you
have replaced all the insulators .
4. Look for unauthorized replacement parts, par-
ticularly transistors, that were install ed during a
previous repair. Point them out to th e customer
and recommend their replacement.
5. Look for part s which, though fun ctio ning , show
obvious signs of deterioration. Point them out
to the customer and recommend their replace-
ment.
6. Check the line cord for cracks and abrasion.
Recommend the replacement of any such line
cord to the custome r.
7. Check the co ndition of the monopole antenna
(if any).
Make sure the end is not broken off, and has
the plastic cap on it. Point out the danger of
impalement on
customer, and
replacement.
a broken antenna to the
recommend the antenna's
8. Check the B+ and HV to see they are at the
values specified. Make sure your instruments
are accurate; be suspicious of your HV meter
if sets alway s have low HV .
9. Check the antenna terminals , metal trim,
"metallized" knobs , screws, and all other
exposed metal parts for AC leakage. Check
leakage as described below.

(0.15V)
Fig. A. Using an AC voltmeter to check AC leakage.
- 4 -
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 microampers) . Leakage
current can be measured by any one of three
methods .
1. A commercial leakage tester , such as th e
Simpson 229 or RCA WT-540A . Follow the
manufacturers ' instructions to use th ese instru-
ments.
2. A battery-operated AC milliammeter. The Data
Precision 245 digital mu.ltimeter 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 examp les of a passive VOM that
is suitable. Nearly all battery operated digital
multimeters that have a 2V AC range are
suitable . (See Fig. A)
HOW TO FIND A GOOD EARTH GROUND
A cold-water pipe is guaranteed eart h groun d ; the
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 shou ld be
zero ohms. If a cold-water pipe is not accessible,
connect a 60 - 100 watts trouble light (not a neon
lamp} between the hot side of the receptacle and the
reta ining screw . Try both slots , if necessary , to locate
the hot side of the line, the lamp should light at
normal brilliance if the screw is at ground potential.
