SAFETY CHECK-OUT (US MODEL)
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 chas-
sis, 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” indication is 0.75 V, so
analog meters must have an accurate low-voltage scale. The Simp-
son 250 and Sanwa SH-63Trd are examples of a passive VOM that
is suitable. Nearly all battery operated digital multimeters that have a
2 V AC range are suitable. (See Fig. A)
