8. Test ENCL. 3 - Enclosure Leakage Current: S.F.C. Open Earth (Ground)
• Applicable to Class 1, Types B, BF and CF.
• Measures leakage current of the exposed metal parts of the instrument under test with Protec-
tive Earth open circuit (S4 = open); normal and reversed polarity using S2.
• For Type BF and CF equipments, measures with the AP/GND switch S3 open and closed.
• Maximum leakage current: 500 µA (Range: DC and AC up to 1 kHz).
9. Test P.L.C. 1 - Patient Leakage Current: Normal Condition
• Applicable to Classes 1 and 2, Types B, BF and CF.
• Measures patient leakage current to earth from all Applied Parts in parallel; normal and re-
versed polarity using S2.
• Maximum leakage current Types B and BF: 100 µA (Range: DC and AC up to 1 kHz). For
Type CF: 10 µA (Range: DC and AC up to 1 kHz).
