LEAKAGE TEST (FOR SERVICE ENGINEERS IN THE
Before reIUming the unit to the user, periorrn 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

2. Replace all protective devices such as
nonmetallic control knobs, insulating
iishpapers, cabinet backs, or shields,
isolation resistor~capacitor networks.
mechanical insulators, etc.

3. Be sure that no shock hazard exists; check for leakage current using
Simpson Model 229 Leakage Tester. standard equipment item
No.2164t, FICA Model WT540A or use alternate method as follows:

Plug the AC line cord directly into a 120-volt AC receptacle (do not use an

lsolaticn 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 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.)
