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 kΩ 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.

2.2.16 Nellcor Compatible Saturation Module, E-NSATX
1. Enter the N/O-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 ‘No
Probe’ should be active (1), when no probe is connected.
3. Connect a Nellcor SpO
2
finger probe to the module. Check that the message ‘No Probe’
changes to ‘Check Probe.’
4. Attach the SpO
2
probe on your finger. Check that a reading of 95-100 and a proper SpO
2
waveform appear.

2.2.17 Masimo Compatible Saturation Module, E-MASIMO
1. Enter the N/O-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 also that the module’s ROM memory has passed the
internal memory test, i.e. the ROM shows OK.
Check that all three error indicators, Preamp Error, QUART Error and I/O Error state NO.
2. Check that the message ‘No probe’ is displayed on the screen when no probe is
connected.
3. Connect a suitable SpO
2
finger probe to the module. Check that the message ‘Check
probe’ is displayed on the screen within 30 seconds.
