• For Type BF and CF equipments, measures with the AP/GND switch S3 open and closed.
• Maximum leakage current: 1000 µA (Range: DC and AC up to 1 kHz).
6. Test ENCL. 1 - Enclosure Leakage Current: Normal Condition
• Applicable to Classes 1 and 2, Types B, BF and CF.
• Measures leakage current of the exposed metal parts of the instrument under test; 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: 100 µA (Range: DC and AC up to 1 kHz).
7. Test ENCL. 2 - Enclosure Leakage Current: S.F.C. Open Supply
• Applicable to Classes 1 and 2, Types B, BF and CF.
• Measures leakage current of the exposed metal parts of the instrument under test, with one
open supply lead interrupted (S1 = 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).
