Patient Leakage Current
This test measures patient leakage current in accordance with IEC60601 ‐ 1, clause 19, for
Class I, Type CF 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. Connect the ECG test cable between the ECG connector on the monitor and the
appropriate input connector on the analyzer.
4. Turn on the monitor.
5. Perform the patient leakage current test as recommended by the analyzer operating
instructions.
6. Repeat the patient leakage current test for the SpO
2
and temperature patient
connections, 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 5.
Note: This test requires a test cable for each patient connector. For example, the ECG
test cable consists of the ECG cable connector, with all conductors shorted
together, connected to a test lead from the electrical safety analyzer. Test cables
for 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.
