LEAKAGE TEST (FOR SERVICE ENGINEERS IN THE U.S.A.)

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

1. Inspect all lead dress to make
certain that leads are not pinched
or that hardware is not lodged
between the chassis and other

SIMPSON MODEL 229 ETC FOR
LEAKAGE TEST

metal parts in the unit.
2. Replace all protective devices such

TO EACH EXPOSED

as nonmetallic control knobs, in
sulating fishpapers, cabinet backs,

or shields, isolation resistor-
capacitor networks, mechanical
insulators, etc.

3. Be sure that no shock hazard exists; check for leakage current
using Simpson Model 229 Leakage Tester, standard equip-
ment item No.21641, RCA Model WI'540A 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

0.15/1F 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 resistor 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 posi-
tions.)

A reading of 0.35 volt RMS or more is excessive and indicates

returning the unit to the owner.
