5.7.2 Earth Leakage Current Test
1. Connect 601 PROXL safety analyzer to a 264 VAC 60 Hz power supply.
2. Connect the application part of the EUT to the RA terminal of the safety analyzer.
3. Use power cord to connect the EUT to the auxiliary power output connector of 601
PROXL safety analyzer.
4. Power on 601 PROXL safety analyzer. Press "4-Earth leakage" on the panel to access
the test interface for earth leakage current test.
5. The earth leakage current is not greater than 300 µA in normal condition and is not
greater than 1000 µA in single fault condition.
5.7.3 Patient Leakage Current Test
1. Connect 601 PROXL safety analyzer to a 264 VAC 60 Hz power supply.
2. Connect the application part of the EUT to the RA terminal of the safety analyzer.

6. The patient leakage current is not greater than 10 µA in normal condition and is not
greater than 50 µA in single fault condition.
5.7.4 Patient Auxiliary Current Test
1. Connect 601 PROXL safety analyzer to a 264 VAC 60 Hz power supply.
2. Use power cord to connect the EUT to the auxiliary power output connector of 601
PROXL safety analyzer.
3. Connect the ECG cable of the EUT to the RA terminal of the safety analyzer.
4. Power on 601 PROXL safety analyzer. Press "8-Patient Auxiliary Current Test" on the
panel to access the test interface for patient auxiliary current test.
5. Press the "APPLIED PART" button repeatedly to select AC and DC measurement.
When DC is selected, the "DC" text is displayed next to the limit.
6. The patient auxiliary current is not greater than 10 µA in normal condition and is not
greater than 50 µA in single fault condition.
