SAFETY CH ECK-OUT

After correcting the original service problem, perform
the following safety checks 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

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 the Simpson 229 or
RCA WT-540A. Follow the manufacturers instructions to
use these instruments.

2. A battery-operated AC milliammeter, 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 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
2V AC range are suitable. (See Fig. A)
