Patient Leakage Current ‐ Mains Voltage on the Applied Part
WARNING: AC mains voltage will be present on the applied part terminals during
this test. Exercise caution to avoid electrical shock hazard.
WARNING: Do not touch the patient leads clips or the simulator parts connected to
patient leads during this test as an electrical shock will occur.
This test measures patient leakage current in accordance with IEC60601 ‐ 1, clause 19, for
Class I, type CF equipment. In this test, 110% of mains voltage is applied between each
patient connection and earth (power ground). Patient leakage current is then measured
from any individual patient connection to earth.
Note: Keep the patient test cable length as short as possible during the leakage test.
Note: This test requires the same test cables for each patient connector as described in
paragraph “ Patient Leakage Current ”.
1. Configure electrical safety analyzer as recommended by analyzer operating
instructions.
2. Connect monitor’s AC mains power cord to analyzer as recommended by analyzer
operating instructions.
3. Connect ECG test cable between ECG connector on the monitor and appropriate
input connector on analyzer.
4. Turn on the monitor.
5. Perform the test as recommended by analyzer operating instructions.
6. Repeat the test for SpO
2
and temperature patient connections, using appropriate test
cables.
Note: Patient leakage current is measured with normal and reverse mains polarity. For
each condition, the measured leakage current must not exceed that indicated in
Table 6.
