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

These specifications are service target specs.

Specifications and components are subject to change without notice.
Overall performance will be maintained or improved.

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 SIMPSON MODEL 229 ETC. FOR

hardware is not lodged between the LEAKAGE 51

eheeehe ehe ehheh meeeh he he assesses: ._®_. 12 massacre

unit. UNIT UNDER TEST ".5 ceouno ex CABLEtCONDUIT, ETC.
2. Replace all protective devices such XELIQEED LEAD

as nonmetallic control knobs, in-

sulating fishpapers, cabinet backs,

adjustment and compartment covers

or shields, isolation resistor- S

capacitor networks, mechanical in- VTVM

sulators, etc. -0 Ac SCALE 0-
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 0.15yF
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
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 ormore is excessive and indicates a potential shock hazard which must be corrected before
returning the unit to the owner.
