To Exposed Metal

Parts on Set

Earth Ground

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 a

VOM or battery-operated AC voltmeter. The "limit" indica-

tion is 0.75V, so analog meters must have an accurate low-

voltage scale. The Simpson 250 and Sanwa SH-63Trd are ex-

amples of a passive VOM that is suitable. Nearly all battery

operated digital multimeters that have a 2V AC range are suit-

able. (See Fig. A)

1. Check the area of your repair for unsoldered or poorly-sol-

dered connections. Check the entire board surface for solder

splashes and bridges.

2. Check the interboard wiring to ensure that no wires are

"pinched" or contact high-wattage resistors.

3. Look for unauthorized replacement parts, particularly transis-

tors, that were installed during a previous repair. Point them

out to the customer and recommend their replacement.

4. Look for parts which, though functioning, show obvious signs

of deterioration. Point them out to the customer and recom-

mend their replacement.

5. Check the line cord for cracks and abrasion. Recommend the

replacement of any such line cord to the customer.

6. Check the B+ voltage to see it is at the values specified.

7. Check the antenna terminals, metal trim, "metallized" knobs,

screws, and all other exposed metal parts for AC leakage.

Check leakage as described below.

SAFETY CHECK-OUT

After correcting the original service problem, perform the following

safety checks before releasing the set to the customer:
