Safety Test (continued)
Chassis Leakage Current Test
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.
Data Sheet for ECG Leakage Current:
The test passes when all readings measure less than the value
shown in the table below. Record all data on the PM Inspection
Certificate.
CAUTION
Line voltage is applied to the ECG leads during this test. To
avoid possible electric shock hazard, the system being tested
must not be touched by patients, users or anyone while the
ISO TEST switch is depressed.
