SAFETY
CHECK.OUT
After correcting the original service problem,
perform the fo[owing safety check before releasing
the setto the customer:
Check
theantennaterminals,metaltrim, "metallized"
knobs, screws,
and all other exposed
metal parts for
AC leakage.Checkleakage
as
described
below.
LEAKAGE TEST
The AC leakagefrom any exposedmetalpartto
earthground
and from allexposed
metal
parts
to any
exposed
metal part havinga return to chassis,
must
not exceed 0.5
mA (500 microampers). Leakage
current can be measuredby any one of three
methods.
l. A commercial leakage tester, such as the
Simpson229 or RCA WT-540A. Follow the
manufacturers'
instructions
to usethese
instru-
ments.
A battery-operatedAC milliammeter.
TheData
Precisign245 digital multimeter is suitablefor
thisjob.
Measuringthe voltage
dropacross a resistor
by
meansof a VOM or battery-operatedAC volt-
meter. The "limit" indication
is 0.75V. so
analog meters must have an accurate low-
voltage scale. The Simpson250 and Sanwa
SH-63Trd
areexamplesof a passive
VOM that
is suitable. Nearly
all battery operateddigital
multimeters that have a 2V AC range are
suitable. (See Fig.A)
