2.
Connect the monitor’s AC plug to the analyzer as recommended in the
analyzer operating instructions.
3.
Connect the analyzer resistance input lead to the equipotential terminal
(grounding stud) on the external power supply. Verify that the analyzer
indicates 150 milliohms or less.
3.4.2 Electrical Leakage
The following tests verify the electrical leakage of the monitor:
•
Earth Leakage Current
•
Patient Leakage Current
•
Patient Source Current (Mains on Applied Part)
3.4.2.1 Earth Leakage Current
This test is in compliance with IEC 601-1 and AAMI Standard ES1,
paragraph 3.3.1, Chassis Source Current, between the power ground and
(Part B) exposed conductive hardware.
1.
Configure the electrical safety analyzer as follows:
Function:
Leakage
Range:
µ
A
2.
Connect the monitor AC plug to the electrical safety analyzer as
recommended by the analyzer operating instructions.
3.
Connect the electrical safety analyzer "leakage" input lead to the
monitor's equipotential terminal.
4.
The equipotential terminal is not connected to ground.
5.
All functional earth terminals are not connected to ground.
