4.3.4 Patient Leakage current

NOTE:
The circuit diagram is based on the Fluke 601Pro series safety Analyzer.
This test measure the leakage current flowing between the selected applied part and the mains PE;
the test with normal and reverse polarity, in normal condition and single fault condition.
Normal condition (NC): with S1, S3, S5 closed, S2, S4 variable.
Single fault condition (SFC): S1, S3 open (one for each time) and S5 closed, S2, S4 variable.
Allowable value:
Normal condition: 10µA (BF applied part), 10µA (CF applied part)
(IEC/EN60601-1, UL60601-1)
Single fault condition: 500µA (BF applied part), 50µA (CF applied part)
(IEC/EN60601-1, UL60601-1)
