No. Check Item Check Procedure Criteria
10. Cardiac Output (CO)
01 Measurement error Using a Waveform or CO Simulator,
input 5 L/min or 15 L/min and measure
the error. Should be within ±10 % of
0.1 to 10 L/min.
Should be within ±15% of
10 to 20 L/min.
Connect a Waveform or CO Simulator,
input blood temperature 36
°
C, 37
°
C,
and 38
°
C, and measure the error.
Blood Temperature should
be within ±0.3

11. External Output (Analog Output)
01 ECG output accuracy Input ECG using a comprehensive
tester.
Connect oscilloscope to output and
observe the waveform.
Should be within ±10% of
output 1V to input 1mV.
Should be within ±0.1V to
input 0mV.
02 BP output accuracy Input BP using a comprehensive
tester.
Connect oscilloscope to output and
observe the waveform. Should be within ±10% of
output 1V to input
100mmHg.
Should be within ±0.1mV to
input 0mmHg.
No Check Item Calibration Reference
12. Calibration
01 Analog When the measurement error of ECG
or BP is great, calibrate individually.
(Exclusive signal generator for
calibration is required.
）
According to the device,
calibration value of each analog
board is stored in each board.
Therefore, when each or all ECG
or Multi AMP boards are replaced,
make sure to incorporate the
boards into the unit, calibrate
them, and write
calibration/compensation value on
the CPU board.
