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

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 LEAKAGE TEST
the chassis and other metal parts

3. Be sure that no shock hazard exists; check for leakage -0 AC SCALEO-

' WT540A or use alternate method as follows: 0"
Plug the power cord directly into a 120-volt AC _.._W\,_
receptacle (do not use an Isolation Transformer for
this test). Using two clip leads, connect a 1500
Ohm, 'IO-watt resistor paralleled by a 0.15 er capacitor, I I
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 g
higher sensitivity to measure the AC voltage drop TEST PROBE (
across the resistor. (See Diagram.) Move the resistor "i
connection to each exposed metal part having a
return path to the chassis (antenna, metal, cabinet, T0 EXPOSED CONNECT T0 KNOWN
screw heads, knobs and control shafts, escutcheon, METAL PARTS EARTH GROUND
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 035 volt RMS or more is excessive and indicates a potential shock hazard which must be corrected
before returning the unit to the owner.
