33. Start NMT measurement (TOF) by selecting NMT Setup and selecting Start-up. Press Previous 
Menu to return to the NMT service menu. 
In the digit field, when the “Supramax search” message changes to “Setting reference,” check 
that the detected supramaximal current is less than 70 mA (the Current set value on the service 
screen is less than 700).   
Check that four successive stimulus pulses are generated in 10-second intervals. During each 
stimulus pulse, a tone sounds and a small asterisk () appears in the digit field. In the digit field, 
check that TOF% is within 95-105, Count is 4, and T1% is within 95-105. 
In the NMT service menu, check that T1%, T2%, T3%, T4% and Ratio% are all within 950-1059.

Then press Previous Menu to return to the NMT service menu. 
In the digit field, check that TOF% is still within 95-105, Count is 4, and T1% is within 95-105. 
Change the stimulus pulse width to 300 µs and check the same parameters. 
 
35. Turn the knob on the NMT simulator to 0 (zero). In the NMT service menu, check that the values for 
T1%, T2%, T3%, T4% turn to 0 and the Ratio% shows – – –. In the digit field, TOF%= should also 
state – – –; Count and T1% should show 0. 
 
36. Turn the NMT simulator knob back to “max.” Change the stimulus mode to Double Burst 
Stimulation (select NMT Setup – Stimulus Mode – DBS).  
Check that only two stimulus pulses are given in a 10-second interval. In the NMT service menu, 
check that T1%, T2%, and Ratio% are still within 950-1059. In the digit field, check that DBS% is 
within 95-105, Count is 2, and T1% is within 95-105. 
 
37. Change the stimulus mode to Single Twitch stimulation (ST). Check that the monitor starts giving 
only one stimulus pulse with a 1-second interval. Note the time when the ST stimulation started. 
In the service menu, check that the T1% value is within 950-1059. In the digit field, the Count 
value should be 1 and T1% within 95-105. 
 
38. Continue single twitch stimulation. Five minutes after the start of ST stimulation, check that the 
NMT measurement stops and the “Measurement OFF” message appears in the NMT digit field. 
 
39. Replace the NMT ElectroSensor with the NMT MechanoSensor. In the NMT service menu, check 
that Cable states PIEZO.

1. Configure the monitor screen to display all parameter information. 
Press the ComWheel to enter the Main Menu and select: 
Monitor Setup – Screen Setup – Waveform Fields/Digit Fields 
An example is shown below:

Field 6 – CO2  
Select Split Screen – None 
To return to the Normal Screen, press the Normal Screen key. 
Connect the patient simulator and check that all parameter information is displayed as configured. 
NOTE: InvBP waveforms are not shown without a patient simulator. 
Preset the measurement settings for parameters as follows, for example: 
ECG - ECG Setup - HR Source - AUTO 
Invasive Pressures 
P1 ‘ART’ Setup – Label – ART 
P2 ‘CVP’ Setup – Label – CVP 
Press the ComWheel to enter the Parameters menu and select:  
Pulse Oximetry – Pleth Scale – AUTO 
Airway Gas – Spirometry Setup – Scaling – Indep. 
 Paw Scale – 20 
 Flow Scale – 15 
Resp Setup  – Size – 1.0 
 Resp Rate Source – AUTO 
 Detection Limit – AUTO 
NOTE: The RESP waveform or Digit Field on the screen must be selected before you can turn on 
the respiration measurement. 
 
2. Connect the patient simulator to the ECG and invBP connectors, connect an SpO2 finger sensor to 
the SpO2 connector, and connect the temperature test plug to a Temp connector. Attach the SpO2 
sensor to your finger. Check that: 
• The simulated waveforms are good. 
• The SpO2 value is in the expected range 
• The Pleth waveform is normal.

Installation and Functional Check 
3. Set the invBP simulator to +100 mmHg (+13.3 kPa) static pressure. Push the ZERO button and 
check that: 
• The invBP waveforms set on the baseline. 
• The digital values go to zero. 
Set the simulator to 0 mmHg (0 kPa) and press ZERO. After the zeroing is completed, turn the 
simulator to dynamic mode and check that the waveform is normal. 
 
4. Check that the “No probe” message is displayed when an SpO2 sensor is not connected. 
Connect an SpO2 finger sensor to the monitor (but not to a finger). Check that “Probe off” or 
“Check probe” is displayed. The Pulse search message may be displayed first. 
 
5. Attach the SpO2 sensor to your finger and check that the pleth waveform is displayed and the 
SpO2 value is in the expected range (95-99%).  
Check that the HR value is calculated from SpO2 when the ECG and InvBP (P1/P2) cables are not 
connected. 
 
6. Remove the SpO2 sensor from your finger and check that “Probe off” or “Check probe” is 
displayed.  
Disconnect the sensor from the monitor and check that “No probe” is displayed. 
 
7. Attach an adult NIBP cuff onto your arm and perform one NIBP measurement. Check that the cuff 
is identified (Adult appears in the NIBP digit field for a short time). 
Check that the measurement result is reasonable. 
 
8. Block the tip of the sampling line with your finger and check that the “Sample line blocked” 
message is displayed on the monitor screen within 30 seconds. 
Detach the D-fend and check that the ”Check D-fend” message is displayed on the monitor 
screen within 30 seconds. 
 
9. Reattach the D-fend. Breathe shortly into the sampling line. Check that the CO2 waveform moves 
up on the screen. 
 
After completing the check, be sure to fill in all necessary documents.
