Check the NIBP watchdog timer activation pressure with a pressure manometer.
6. Check the NIBP watchdog timer by performing Watchdog – Test Adult and Test Infant .
7. Check the safety valve by performing Safety Valve – Adult and Infant .
8. Attach an adult NIBP cuff onto your arm and perform one NIBP measurement. Check the
module identifies the cuff, i.e. the text ‘Adult’ appears in the NIBP digit field for a short
time.
Check that the module gives a reasonable measurement result.

2.2.17 NeuroMuscular Module, E-NMT, M-NMT
1. Enter the NMT module 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 that the module’s memories have passed the internal
memory test, i.e. RAM, ROM and EEPROM all state OK.
2. Check the function of the front panel membrane keys
Start-Up
and
Stop/Continue
.
3. Check that the message ‘Cable off’ is shown in the digit field and that ‘Cable’ on the
service menu states
OFF .
Plug the NMT Sensor Cable with the NMT ElectroSensor into the front panel connector
NMT. Check that the message in the digit field changes to ‘Measurement OFF’ and ‘Cable’
in the service menu states
EMG and ELECTR. OFF .
4. Place a 3 k
Ω
resistor between the ElectroSensor’s stimulus electrode leads (brown and
white). Perform Start Curr. Test.
Check that the test was successful, i.e. the ‘Current test (mA):’ in the menu states 30 OK, 50
OK and 70 OK .
Connect the ElectroSensor leads to the NMT simulator. Set the switch on the simulator to
FADE OFF and turn the knob to MAX. Check that ‘Cable’ in the service menu states now
only
EMG .
5. Start the NMT measurement (TOF) by pressing the
START-UP
key on the module.
Check that the found supramaximal current is less than 70 mA, i.e. the ‘Current set’ value
in the service menu is less than 700.
6. Check that the digit field TOF% value is within 95-105, Count is 4 and T1% is within
95-105.
7. Check that the Noise value in the service menu remains under 100.

2.2.18 Nellcor Compatible Saturation module, E-NSATX, E-NSAT, M-NSAT
1. Enter the M-SAT 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 that the NSAT module’s ROM memory has passed the
internal memory test, i.e. ROM shows OK.
Check that all three error indicators, Preamp Error, QUART Error and I/O Error state NO.
2. Check that the SpO
2
probe related status information in the menu is correct. Only the
‘NoProbe’ should be active (1), when no probe is connected.
