8.2.8 Patient (source) leakage current tests

This procedure measures the leakage current from an applied part connector of the device to
ground.
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 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.
NOTE: Perform this test for all the connected parameter modules and patient connectors
specified in
1. Configure the safety analyzer as follows (NC):
