Check that the HR value is calculated from P1, when ECG is not measured (ECG cable
disconnected).

SpO
2
measurement
18. SpO
2
probe detection
Check that the message ‘No probe’ is shown, when no SpO
2
sensor is connected to the
module. Connect an SpO
2
finger probe to the module (with the interconnection cable, if
needed). Check that the message ‘Probe off’ is shown when the probe is not connected to
a finger.
"
19. Test measurement
Connect the SpO
2
probe onto your finger. Check that the reading of 95-99 and SpO
2
waveform appears. Check that the HR value is calculated from SpO
2
when ECG and InvBP
(P1) are not measured.
NOTE: a functional tester cannot be used to assess the accuracy of a pulse oximeter probe or a
pulse oximeter monitor

Non Invasive Blood Pressure measurement
20. Communication and memories
Enter the NIBP module service menu:
Parameters - NIBP
Check that the Time-outs, Bad checksums and Bad c-s by mod values are not increasing
faster than by 5 per second. Check also that the NIBP board memories have passed the
internal memory test, i.e. the RAM, ROM and EEPROM show all OK.
"
21. Pump and valves
Check the pump and valves.
Select
Pneumatics from the NIBP menu. Connect a pressure manometer to the NIBP
module cuff connector.
Select
Start Pump and press the ComWheel. Check that the pump turns on and the
pressure inside the tubing system starts to increase. Stop the pump by pressing the
ComWheel again when the pressure reaches 280 mmHg.
Select
Open Exh2 . Press the ComWheel and check that the pressure inside the tubing
system starts to drop, then press the ComWheel again. If necessary, turn the pump on
again for a moment to increase the pressure inside the tubing system.
Select
Set Valve . Press the ComWheel and set the value under the text Pulse Valve to
number 150 by turning the ComWheel. Press the ComWheel again and check that the
pressure inside the tubing system starts to drop. Finish the test by selecting
