LEAKAGE TEST

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- SIMPSON MODEL 229 ETC-FOR

tween the chassis and other metal LEAKAGE TEST

ers or shields, isolation resistor-

capacity networks, mechanical in-

sulators, etc.
3. Be sure that no shock hazard exists; check for leakage

current using Simpson Model 229 Leakage Tester, 6

standard equipment item No. 21641, RCA Model

WT540A or use alternate method as follows: VTVM

Plug the AC line cord directly into a 120»volt AC -0AC SCALEO-

receptacle (do not use an Isolation Transformer for

this test). Using two clip leads, connect a 1500 ohm, 151'; 3VHM
10«watt resistor paralleled by a 0.15mf capacitor, in M
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 _I '-
higher, sensitivity to measure the AC voltage drop 0.15 MF
across the resistor. (See Diagram.) Move the resistor
connection to each exposed metal part having a

I- screw heads, knobs and control shafts, escutcheon,
etc.) and measure the AC voltage drop across the To EXPOSED CONNECT To KNOWN

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.
