3.6.2 Earth Leakage Current Test
1. Connect the 601 safety analyzer to a 264 V AC 60 Hz power supply.
2. Connect the application part of the EUT to the RA terminal of the safety
analyzer.
3. Use the power cord to connect the EUT to the auxiliary power output connector
of the 601 safety analyzer.
4. Power on the 601 safety analyzer. Press 4-Earth leakage on the panel of the
601 safety analyzer to access the screen for earth leakage current test.
5. The earth leakage current is not greater than 500 µA in normal condition and is
not greater than 1000 µA in single fault condition.
3.6.3 Patient Leakage Current Test
1. Connect the 601 safety analyzer to a 264 V AC 60 Hz power supply.
2. Connect the application part of the EUT through the application part connection
tooling. Connect the SUM terminal of the application part connection tooling to
the RA terminal of the safety analyzer.
3. Use the power cord to connect the EUT to the auxiliary power output connector
of the 601 safety analyzer.
4. Power on the 601 safety analyzer. Press 6-Patient leakage on the panel of the
601 safety analyzer.
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 leakage current is not greater than a
.c. 10 μA and d.c.10 μA in
normal condition and is not greater than a.c. 50 μA and d.c.50 μA in single fault
condition.
If the electrical safety test fails, please contact our Customer Service Department.
3.7 Cleaning and Disinfection
3.7.1 Cleaning
The equipment should be cleaned regularly, and in areas with serious
environmental pollution or large wind and sand, the frequency of cleaning should
be increased. Please consult or understand the hospital's regulations on
equipment cleaning before cleaning.
The recommended cleaning agents are: hydrogen peroxide (3%), ethanol (70%),
and isopropanol (70%).
When cleaning the equipment:
1. Turn off the power and disconnect the power cord.
2. Use a soft cotton ball. After absorbing an appropriate amount of cleaning agent,
wipe the LCD.
