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 BF 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
above Patient Leakage Current.
1. Configure electrical safety analyzer as recommended by analyzer operating
instructions.
2. Connect the monitor’s AC mains power cord to analyzer as recommended by analyzer
operating instructions.
3. Apply NIBP cuff wrapped tightly around an appropriate metal cylinder.
4. Connect a test cable between the cylinder and an input connector on analyzer.
5. Turn on

.
6. Perform test as recommended by analyzer operating instructions.
7. Repeat test for SpO

and temperature patient connections, if those options configured,
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 5.

Patient Auxiliary Current
This test measures patient auxiliary current in accordance with IEC60601-1, clause 19, for
Class I, type BF equipment. The applied voltage for IEC60601-1 the voltage is 264 volts,
50 to 60 Hz. Patient auxiliary current is measured between each test cable for all possible
connections.
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
Patient Leakage Current.
