LEAKAGE TEST (FOR SERVICE ENGINEERS IN THE USA.)
Belore 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 hard-
ware is not lodged between 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 covers
or shields, isolation resistor-capacity
networks, mechanical insulators. 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. stan-
dard equipment Item No. 21641, RCA Model WT540A or
use alternate method as follows:

Plug the power cord directly into a 120-volt AC recep-
tacle (do not use an Isolation Transformer for this test).
Using two clip leads, connect a 1500 Ohm, 10-watt resis-
tor paralleled by a 0.15 pF capacitor. in series with all ex-
posed 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, cabi-
net, screw heads, knobs and control shafts, escutcheon,
etc.) and measure the AC voltage drop across the resis-
tor. (This test should be performed with the power switch
in both the On and Off positions.)

A reading of 035 volt RMS or more Is excessive and indi-
cates a potential shook hazard which must be corrected
before returning the unit to the owner.
