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 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 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 volt-
meter. The “limit” indication is 0.75V, 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)
