SAFETY CHECK-OUT
After correcting the original service problem, perform the 3. Measuring the voltage drop across a resistor by means of a
following safety checks before releasing the set to the customer: VOM or battery-operated AC voltmeter. The "limit" indication
Check the antenna terminals, metal trim, "metallized" knobs, screws, is 0.75 V, so analog meters must have an accurate low-voltage
and all other exposed metal parts for AC leakage. Check leakage as scale. The Simpson 250 and Sanwa SH-63Trd are examples of
described below. a passive VOM that is suitable. Nearly all battery operated
digital multimeters that have a 2V AC range are suitable. (See
LEAKAGE Fig. A)
The AC leakage from any exposed metal part to earth ground and
To Exposed Metal
Parts on Set
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
AC
WT-540A. Follow the manufacturers' instructions to use these
0.15 µ F 1.5k Ω voltmeter
instruments. (0.75V)
2. A battery-operated AC milliammeter. The Data Precision 245
digital multimeter is suitable for this job.
