6. Module software (serial numbers)
Enter the service menu:
Monitor Setup -  Install/Service  (password 16-4-34) - 
Service  (password 26-23-8)
Take down the information regarding the module software by selecting  Scroll Vers and 
turning the ComWheel.

7. Communication and memories
Enter the   Parameters -  ECG  service menu.

11. Test with the patient simulatorConnect the leads to a patient simulator.
Perform the settings and checks with Dynatech Nevada MedSim 300 Patient Simulator:
ECG - BASE - BPM - 160
           PACE - WAVE - NSR
Check that a normal ECG waveform is shown, the HR value is 160 (±5) and the ‘Pacer 
count’ value is not increas ing in the service menu.
ECG - PACE - WAVE - ASNC
Check that pacemaker spikes are shown on  the ECG waveform,...

Temperature measurement
14. Communication and memoriesEnter the ESTP: STP service menu:
Parameters - ESTP : STP
Check that the Time-outs, Bad checksums and Bad c-s by mod values do not increase 
faster than by 5 per second. Check also that the STP board memories have passed the 
internal memory test, i.e. the  RAM, ROM and EEPROM show all OK.

15. Temperature probe detection
Check that the ‘Cable’ and ‘Probe’ show OFF for both channels, T1 and T2, when no 
probes...

Invasive blood pressure measurement
19. Membrane keysCheck the front panel membrane keys that are related to the InvBP measurement.
Press each of the keys for at least one second. Check that the pressed key is identified, i.e. 
one of the texts for Buttons changes fr om OFF to ON in the service menu.

20. Cable and transducer detection
Check that the Cable and Probe for P1 show  OFF. Connect the InvBP adapter cable to the 
module,...

24. Test measurementConnect the SpO
2 probe onto your finger. Check that the reading of 95-99 and SpO2 
waveform appears. Check that the HR value is calculated from SpO
2 when ECG and InvBP 
(P1) are not measured.

Non Invasive Blood Pressure measurement
25. 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...

Wait for 15 seconds for the pressure to stabi lize then check that the pressure does not 
drop more than 6 mmHg per one minute. Release the pressure by pressing the 
ComWheel once more.

29. Calibration check
Recalibrate the NIBP measurement accordin g to the instructions in section “NIBP 
calibrations” on page 44. Remember to set the calibration protection back on after the 
calibration.
Disconnect the pressure manometer. Select...

32. Test measurementCheck that the automatic inflation limits are in use:
NIBP - NIBP Setup - Inflation Limits - Auto - Previous Menu
Connect the cuff onto your arm, select  Start Ven.Stasis in the NIBP menu and press the 
ComWheel. Check that the module identifies  the cuff, i.e. the text Adult appears in the 
NIBP digit field for a short moment.
Keep the pressure inside the cuff for about half  a minute in order to find out that the cuff 
is not leaking, then...
