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
chassis and other metal parts in the

TO EACH EXPOSED
METAL SURFACE OF
unit UNIT UNDER TEST ma...

2. Replace all protective devices such
as nonmetallic 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 WT540A 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 0.15pF
capacitor, 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
