Patient Leakage Current
This test measures patient leakage current in accordance with IEC60601-1, clause 19, for
Class I, Type BF equipment. Patient leakage current in this test is measured from any
individual patient connection to earth (power ground).
1. Configure the electrical safety analyzer as recommended by the analyzer operating
instructions.
2. Connect the monitor’s AC mains power cord to the analyzer as recommended by the
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 the patient leakage current test as recommended by the analyzer operating
instructions.
7. Repeat the patient leakage current test for SpO
2
and temperature patient connections,
if those options configured, using the appropriate test cables.
Note: Patient leakage current is measured under various conditions of the AC mains and
protective earth conductor. For each condition, the measured leakage current must
not exceed that indicated in Table 4.
Note: This test requires a test cable for each patient connector. Test cables for NIBP, SpO
2
and temperature can be configured in a similar manner, by wrapping each sensor
end individually with aluminum foil filled with conductive gel (only enough gel to
ensure conductivity). Attach a wire to the foil that is connected to a test lead from
the electrical safety analyzer.
