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 cables for each patient connector as described in
paragraph “ 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.
3. Connect the patient test lead combination in Table 7 to the appropriate input
connector on the electrical analyzer.
4. Turn on the monitor.
5. Perform patient auxiliary current test per Table 8 as recommended by electrical
analyzer’s operating instructions.
6. Repeat the patient auxiliary current test for each test lead combination as listed in
Table 7 and measure each patient auxiliary current.
