Enclosure Leakage Current (Touch Current) Test - GE HEALTHCARE CARESCAPE Monitor B650 Technical Manual

9. Read and record the current leakage indicated on the safety tester.
10. Power off the device under test.
Acceptance criteria in Normal Condition (NC):
• All readings shall be less than or equal to 300 μA for installations that require compliance
to UL 60601-1 requirements.
• All readings shall be less than or equal to 500 μA for installations that require compliance
to EN 60601-1 / IEC 60601-1 requirements.
Acceptance criteria in Single Fault Condition (SFC) – one of the supply conductors open at a
time:
• All readings shall be less than or equal to 1 mA.

8.2.6 Enclosure leakage current (touch current) test

This test measures current leakage through the exposed conductive parts on the device under
test.
Perform the test in Normal Condition (NC) and in two different Single Fault Conditions (SFC):
1) earth open and 2) one of the supply conductors open at a time. Perform the test with normal
and reverse polarity.
NOTE: Refer to the instructions delivered with the safety analyzer to perform this test.
NOTE: *The measuring device (MD) represents the network and voltage measuring instrument
and its frequency characters according to IEC 60601-1.
1. Configure the safety analyzer as follows (NC):
−
−
−
2. Power on the device under test.
Polarity: NORMAL
Neutral: CLOSED
Earth (GND): CLOSED
