LEAKAGE TEST (FOR SERVICE ENGINEERS N THE USA)
Before returning the unit to the user, perform the following safety checks:

1.

l"

inspect all lead dress to make
certain that leads are not pinched
or that hardware is not lodged
between the chassis and other
metal parts in the unit.

Be sure that any protective de
vices such as nonmetallic control
knobs, insulating fishpapers,
cabinet backs, adjustment and
compartment covers or shieldsr
isolation resistor-capacity net-
works, mechanical insulators, etc.
which were removed for servicing
are properly reinstalled.

. 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
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 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.
