A and must be replaced with parts having specifications 2. Leakage Current Measurement (For 120V Model Only). When service has been completed, it i s imperative that you verify that all exposed conductive surfaces are properly insulated from supply circuits. @ @ Meter impedance should be equivalent to 1500 ohm shunted by 0.1 5pF. Leakage current must not exceed 0.5mA. Be sure t o test for leakage with the AC plug in WALL both polarities.
