3.2.6.4 Testing display accuracy of SpO2 and pulse rate
Check displayed values on the LCD screen using the following simulator settings:
Simulator value SpO2 Value displayed
95.5% 92% - 99%
90.6% 87% - 94%
85.5% 82% - 89%
Simulator value pulse rate Value displayed
70 bpm 66 bpm - 74 bpm
100 bpm 96 bpm - 104 bpm
160 bpm 155 bpm - 165 bpm
Activate interference test on the simulator by pressing key and keep it pressed, the SpO2
value must remain displayed on the screen.
Disconnect the SpO2 plug from the monitor. The message “No SpO
2
” passive appears,
accompanied by an intermittent audible alarm signal.
Press (8) button, alarm is silenced.
Connect up finger probe and check it is working correctly.
3.2.7 Invasive blood pressure performance check (Vers. 2.0 and higher)
Comment: This test is to be applied to both blood pressure channels. For devices with
rounded connectors use the dual transducer cable.
Activate “Alarms OFF”, LED (9) should be illuminated.
Preparing the multifunction simulator:
Plug pressure simulator cable into simulator input “Blood Pressure 1” (120/80).
Settings:
Polarity -----------> pos.
Sensitivity -----------> 5uV/V
mmHg -----------> 0
Connect up simulator to monitor and press F3 [NIP/PRESS] in the main menu, followed
by selecting [Mode INVASIVE] with F4 and perform zero adjustment. Select the following
pressure values and check display is within tolerance limits.
200 mmHg +/- 6 mmHg
100 mmHg +/- 4 mmHg
30 mmHg +/- 3 mmHg
Set simulator to “wave” and activate pressure waveform on the monitor. A pulsating pres-
sure waveform displaying the following digital values should appear on the screen:
