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

achassis, must not exceed 0.5mA (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-54OA. Follow the
manufacturers instructions to use these instru-
ments.

2. A batteryioperated AC milliammeter. The Data
Precision 245 digital multimeter is suitable for
this job.

8. 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 low-voltage scale.
The Simpson 250 and Sanwa SHABSTrd are
examples of a passive VOM that is suitable.
Nearly all battery operated digital multimeters
that have a 2V AC range are suitable.
