TO SERVICE PERSONNEL
Leakage Current Measurement (For 120 V Models
Only).
When service has been completed, it is imperative to
verify that all exposed conductive surfaces are
properly insulated from supply circuits.
• Meter impedance should be equivalent to 1500 ohm
shunted by 0.15
µ
F.
• Leakage current must not exceed 0.5 mA.
• Be sure to test for leakage with the AC plug in both
polarities.
• POLARIZATION (U, C models)
This product is equipped with a polarized alternating-
current line plug (a plug having one blade wider than
the other). This plug will fit into the power outlet only
one way. This is a safety feature.
