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.
L E A K A G E T E S T
The AC leakage from any exposed metal part to
earth gtound 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 bv anv one of three
methods.
I .
A
commercial leakage tester, such as the
Simpson 229 or RCA WT-540A.
Follow the
manufacturers' instructions to use these instru-
m e n t s .
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 0.75 V, 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 2 V AC range are
suitable. (See Fig. A)
