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 cer-
tain that leads are not pinched or
that hardware is not lodged be-
tween the chassis and other metal
parts in the unit.
2. Be sure that any protective de-
vices such as nonmetallic control
knobs, insulating fishpapers,
cabinet backs, adjustment and
compartment covers or shields,
isolation resistor-capacity net-
works, mechanical insulators, etc.
which were removed for servicing
are properly reinstalled.
3. Be sure that no shock hazard exists; check for leak-
age current using Simpson Model 229 Leakage
Tester, standard equipment item No. 21641, RCA
Model WT540A or use alternate method as follows:
Plug the power cord directly into a 120-volt AC
receptacie (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 uF capacitor, in
series with all exposed metal cabinet parts and a
known earth ground, such as a water pipe or con-
duit. 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 resis-
tor 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.
