Please refer to ‘Chassis leakage current test’ on page 10-33 for
the information.
Isolated Patient Lead (Source) Leakage - Lead to Lead
Refer to the procedure in the IEC 60601-1.
Isolated Patient Lead (Sink) Leakage-Isolation Test
Refer to the procedure in the IEC 60601-1.
NOTE: It is not necessary to test each lead individually or power
condition combinations as required in previous tests.
