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
3.4.2.3 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 N5500 and appropriate input
connector on analyzer.
4. Turn on N5500.
5. Perform test as recommended by analyzer operating instructions.
6. Repeat test for SpO

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.

3.4.2.5 Patient Auxiliary Current
This test measures patient auxiliary current in accordance with IEC60601-1, clause 19,
for Class I, type CF equipment. The applied voltage for IEC60601-1 the voltage is 264
volts, 50 to 60 Hz. Patient auxiliary current is measured between each ECG test lead and
between each sensor connection 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 cable s for each patient connector as described in
3.4.2.3 Patient Leakage Current.
1. Configure the electrical safety analyzer as recommended by the electrical analyzer’s
operating instructions.
2. Connect the monitor’s AC mains power cord to the electrical analyzer as
recommended by the electrical analyzer’s operating instructions.
