Concentration (Optional)
01 CO
2
Concentration
Calibration
(HCP-810/820)
Perform calibration according to the procedure
explained in "Chapter 9 Maintenance Check"
(Maintenance Manual). The calibration should complete without
error.
02 CO
2
Concentration
Measurement
Perform measurement with 5% calibration gas,
and check the displayed CO
2
concentration value
on the monitor.
The displayed CO
2
concentration value
should be within 38 mmHg ± 2 mmHg.
No Check Items Check Procedure Criteria
13. BIS (Optional)
01 Sensor Detection Connect the signal generator and BIS sensor
simulator, and check that the brain wave is
displayed. Brain wave should be displayed on the
monitor.
No Check Items Check Procedure Criteria
14. Analog Output
01 ECG Output Accuracy Input 10 Hz sine-wave signal of 1mV (2mVp-p)
amplitude from the simulator, connect the
oscilloscope to the output, and check the displayed
waveform.
The displayed waveform amplitude should
be within 1 V ± 0.1 V (2 Vp-p ± 0.2 Vp-p).
02 BP output accuracy Input BP signal of 0 mmHg, 100 mmHg, 250 mmHg
from the simulator, connect the oscilloscope to the
output, and check the displayed waveform. The displayed output voltage should be
within 0 V ± 0.1 V at 0 mmHg,
1 V ± 0.1 V at 100 mmHg.
No Check Items Check Procedure Criteria
15. Periodic Replacement Parts, Aftertreatment
01 NIBP Unit Check the number of measurements. It should not exceed 100,000 times.
02 Lithium-Ion Battery
Pack BTO-008 Check the number of charging/discharging times or
the first usage date. The number of charging/discharging times
should not exceed 300 times, or usage
duration should not exceed one year.
03 CO
2
Unit
(When HCP-810/
HCP-820 is used)
Check the usage hours. It should not exceed 30,000 hours.
04 Restore Backup Data After the check procedure, restore the setup data
from the SD card or USB memory.
If the setting information before the check
procedure have been written down, restore the
settings to original state as written. The settings should be properly restored
to original state.

16. Electrical Safety
01 Earth Leakage
Current (NC) Measure the earth leakage current under normal
condition using a leak measurement safety tester.
Test according to the test method of IEC 60601-1. Earth Leakage Current (NC) should be 5
mA or less.
02 Earth Leakage
Current (SFC) Measure the earth leakage current under single
failure condition using a leak measurement safety
tester.
Test according to the test method of IEC 60601-1. Earth Leakage Current (SFC) should be
10 mA or less.
03 Patient Leakage
Current (NC)
(From patient
connection to earth) Measure the patient leakage current under normal
condition using a leak measurement safety tester.
Test according to the test method of IEC 60601-1. [AC/DC]
Patient Leakage Current (NC) 0.01 mA or
less
(CF Type)
04 Patient Leakage
Current (SFC)
(From patient
connection to earth) Measure the patient leakage current under single
failure condition using a leak measurement safety
tester.
Test according to the test method of IEC 60601-1. [AC/DC] Patient Leakage Current (SFC)
0.05 mA or less
(CF Type)
