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 forAC 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 microamperes).

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 aVOM

or battery-operatedAC 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)
