LEAKAGE TEST (FOR SERVICE ENGINEERS IN THE U.S.AI

Before returning the unit to the user, perform the
following safety checks:

1. Inspect all lead dress to make
certain that leads are not pinch-
ed orthat hardware is not lodged
between the chassis and other
metal parts in the unit.

2. Replace all protective devices
such as nonmetallic control
knobs, insulating fishpapers,
cabinet backs. or shields, isola-
tion resistorcapacitor networks,
mechanical insulators, etc.

3. Be sure that no shock hazard exists; check for
leakage current using Simpson Model 229 Leakage
Tester, standard equipment item No. 21641, RCA
Model WT540A or use alternate method as follows:

Plug the AC line cord directly into a 120-volt AC
receptacle (do not use an Isolation Transformer for
this test). Using two clip leads, connect a 1500 ohm,
10-watt resistor paralleled by a 0.15mF capacitor, in
series with all exposed metal cabinet parts and a
known earth ground, such as a water pipe or conduit.
Use a VTVM or VOM with 1000 ohms per volt, or
higher sensitivity to measure the AC voltage drop
across the resistor.(See Diagram.) Move the reisistor
connection to each exposed metal part having a return
path to the chassis (antenna, metal, cabinet, screw
heads, knobs and control shafts, escutcheon, etc.) and
measure the AC voltage drop across the resistor. (This
test should be performed with the power switch in
both the On and Off positions.)

A reading of 0.35 volt RMS or more is excessive and indicates a potential shock hazard which must be corrected

before returning the unit to the owner.
