Components havingspeciai characteristics are marked and WALL EQUIPMENT TESTER on
must be replaced with parts having specifications equal to OUTLET UNDER TEST EQUIVALENT
those originally installed.
2. Leakage Current Measurement (For 1.20V Models Only). ® :ID
When service has been completed, it is imperative to verify
that all exposed conductive surfaces are properly insulated =
from supply circuits. lNSfilflNG
0 Meter impedance should be equivalent to 1500 ohm shunted
by 0.15uF. ,
c Leakage current must not exceed 0.5mA.
0 Be sure to test for leakage with the AC plug in both
polarities.
