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.
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 th at the ECG/RESP board memories have passed 
the internal memory test, i.e. the RAM, ROM and EEPROM state all OK.

8. Power frequency
Check that the power frequency value is set according to the current mains power 
frequency. Change the setting by selecting  Power Freq, if necessary.

9. Cable recognition
Connect a 12-lead ECG trunk cable without a lead set to the module. Check that the 
message ‘Leads off’ is displayed on the screen.

10. Lead detectionConnect both 5-leadwire sets to the trunk  cable. Connect all the leads together, for 
example to a suitable screwdriver. Check th at all the electrodes show ON and the 
message ‘Asystole’ appears. Check that the Cable type shows 10 lead.
Connect the 10-leadwire set to the simulator. Disconnect one of the leads and check that 
the corresponding electrode in the service  menu shows OFF within 10 seconds of the 
disconnection, and then reconnect the lead. Check the rest of the leads using the same 
method. Disconnect the trunk cable.
Connect a 3-leadwire set to a trunk cable and  connect it to the module. Connect all the 
leads together, for example to a suitable screwdriver. Check that the cable type shows 3 
lead.
NOTE: When any of the limb le ads is disconnected, the measurement will automatically 
change to 3 electrode ECG measurement.
NOTE: The asystole and different leads off  messages are shown using certain priority. 
Even though one of the leads is disconnected, the related leads off message may not 
appear on the screen.
NOTE: When RA, LA, LL or RL electrode is di sconnected, all six V electrodes show OFF.

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, the HR value changes to 
75 (±5) and the Pacer count valu e is increasing according to the shown pacemaker spikes.
Set the pacemaker option off:
ECG - PACE - WAVE - NSR

Respiration measurement
12. RESP measurement recognition Check that Resp Available and RESP Measurement both show ON in the ESTP: ECG service 
menu.

13. Test with patient simulatorCheck the respiration measurement with a patient simulator.
The settings and checks with Dynatech Nevada MedSim 300 Patient Simulator:
Simulator Cover:
BASELINE IMPEDANCE -switch
 - 500
LEAD SELECT-switch
 - II/RL-LL
Simulator Menu:
RESP - WAVE - NORM
RATE - 20
OHMS - 1.0
RATIO - 1/1
APNEA - OFF
SHIFT - OFF
Check that the RESP waveform is shown and the RR value is 20 (±5). Change the position 
of the BASELINE IMPEDANCE switch and check that appropriate RESP waveform and RR 
value are shown again within 30 seconds.
RESP - APNEA - 32 S
Check that the monitor activates the APNEA alarm.
NOTE: Make sure that only the ECG leads are connected to the simulator during the apnea 
test. If other cables are connected at the same time, the respiration signal from the 
simulator may be disturbed, and therefore, the APNEA alarm may not be activated.
NOTE: When you have the ECG service menu open, spikes will appear on the respiration 
waveform. These spikes represent the threshold level for detecting inspiration and 
expiration.

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 are connected.
Connect the temperature adapter cable to  the module temperature connector and a 
temperature test plug to the adapter cable. Check that the Cable and Probe for T1 show 
ON and the corresponding temperature value appears on the monitor screen.
Perform the same check also for the channel T2.

16. Calibration check

shown beside the text Configuration in the service menu and it can be either STP or ST. 
Change the configuration in the  Calibrations - Set Config menu, if necessary. To activate 
the change, reset the module communicatio n by removing and inserting the module.

(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 the NIBP board memories have passed the 
internal memory test, i.e. the  RAM, ROM and EEPROM show all OK.

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  Calibrations - Calibration Check . Press the 
ComWheel and take down the zero offset values for both pressure transducers, B1 and 
B2. The values should be within ±20 mmHg.
Connect the pressure manometer to the cuff connector and check the calibration with 
pressures 100 mmHg, 200 mmHg and 260 mmHg. The zero offset value must be added to 
the displayed pressure value in order to determine the real pressure.

30. Safety valve functions
Select  Safety Valve  from the NIBP service menu.
Disconnect the pressure manometer from th e NIBP module cuff connector. Connect the 
NIBP hose and cuff to the NIBP module cuff connector.  Perform the check with a 
standard adult cuff that is connected  around some round object, for example a 
calibration gas bottle.  
Select  Start Test . Start the adult safety valve test by pressing the ComWheel. Wait until 
the pump stops and the pressure is deflated. 
Open cuff connector or disconnect an d connect cuff connector from module
