LEAKAGE TEST (FOR SERVICE ENGINEERS IN THE U.S.A.I

Before returning the unit to the user, perform the following safety checks:

SIMPSON MODEL 229 ETC. FOR
LEAKAGE TEST

1. Inspect all lead dress to make certain
that leads are not pinched or that
hardware is not lodged between

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 235,

WT540A or use alternate method as follows:

Plug the power cord directly into a 120-volt AC WV
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 015%

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 TEST PROBE
across the resistor. (See Diagram.) Move the resistor . (

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.
