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 (500 microampers).
current
methods,

Leakage
can be measured by any one of three

1. A commercial leakage tester. such as the
Simpson 229 or RCA WT-54OA. Follow the
manufacturers instructions to use these instru»
ments.

2. A battery-operated AC milliammEter. The Data
Precisron 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 0.75V. so
analog meters must have an accurate
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 3 2V AC range are
suitable. (See Fig. A)
