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
chassrs and other metal parts In the :flgffingEggggE%F
unlt- UNIT UNDER TEST

2. Replace all protective devices such
as nonmetellic control knobs, in-
sulating fishpapers, cabinet backs,
adjustment and compartment covers
or shields, isolation resistor-
capacitor networks, mechanical in-
sulators, etc.

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 WT54DA 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 pans 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 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.
