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-

l tween the chassis and other metal
parts in the unit.

2. Be sure that any protective devices
such as nonmetallic control knobs,
insulating fishpapers, cabinet backs,
adjustment and compartment cov-
ers or shields, isolation resistor-
capacity networks, mechanical in-
sulators, etc. which were removed
for servicing are properly reinstalled.

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 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 0.15pF capac-
itor, 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
resistoi 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.)

returning the unit to the owner.
