6. Under the condition of normal power input polarity A (normal condition A), measure the
ground leakage current, enclosure leakage current and patient leakage current. After
cutting off the system power, under the condition of reversed power input polarity
(normal condition B), measure the ground leakage current, enclosure leakage current
and patient leakage current.
