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 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.
Ls
A commercial leakage tester, such as the
Simpson 229 or RCA WT-S540A. Follow the
manufacturers’ instructions to use these instru-
ments.
A battery-operated AC milliammeter. The Data
Precision 245 digital multimeter is suitable for
this job.
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)

ELECTRICAL PARTS LIST
NOTE:
@ Due to standardization, replacements
in the parts list may be different from
the parts specified in the diagrams or
the components used on the set.
@ items marked “*” are not stocked since
they are seldom required for routine
service. Some delay should be antici-
pated when ordering these items.
METAL : Metal-film resistor
METAL OXIDE : Metal Oxide-film resistor
F : nonflammable
@ SEMICONDUCTORS
In each case, u:y, for example:
uA: WA, UPA: BPA,
WP Bis Jer Bs UP Chee Ps
UP Dees eR Dee
@ -—XxX, —X mean standardized parts, so @ CAPACITORS
they may have some differences from the uF: wF
