3. Measuring the voltage drop across a resistor by means of aVOM
or battery-operated AC voltmeter. The “ limit” indication is
0.75V, soanalog meters must have an accurate low-voltagescale.
The Simpson 250 and Sanwa SH-63Trd are examples of a pas-
sive VOM that is suitable. Nearly all battery operated digital
multimeters that have a 2V AC range are suitable. (See Fig. A)

SAFETY CHECK-OUT
After correcting the original service problem, perform the follow-
ing safety check before releasing the set to the customer :
Checkthe antenna terminals, metaltrim,“metallized”knobs,screws,
and all other exposed metal parts forAC leakage. Check leakage as
described below.
LEAKAGETEST
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 0.5mA (500 microampers).
Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or
RCAWT-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.
