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 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

and temperature patient

connections, using the appropriate test cables.

Note: Patient leakage current is measured under various conditions of the AC power 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

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.
