4.8 NMT
Service menu for Neuromuscular Transmission Module, 
E-NMT or M-NMT.
Start Curr. test is a test where the module itself checks 
the difference between a given current and the measured 
current. A 3 k
Ω resistance should be connected between 
the stimulus electrodes before starting the test. All the 
currents checked will be displayed on the service data 
screen. After the current value, the status of the test is 
shown. If the test is not passed, send the module back to 
the factory for calibration.
T1%/ref T1% / ref gives a selection for changing settings 
related to the NMT MechanoSensor. A setting of 3 should 
always be used for normal monitoring. The settings 1 and 
2 are for research purposes only.
Record Data prints out the displayed service data and 
circuit board information (id., serial number, and 
software id.) on the recorder.
Service Data
Cable shows the type of cable being used.
Cable check value shows the bit amount. To check the value for each cable, see the following chart:
- EMG                      -100...+100
- Cable OFF            >1950
- Piezo                    900...1100
- Regional block   600....800
Module keys checks the function of the module keys. A blue background appears at the back of the text when a key 
is pressed for more than one second.
Stimulus mode shows the selected stimulus. Stimulus mode can be changed using the NMT Setup menu.
Measurement indicates ON/OFF.
T1%, T2% shows the measured response. A value of 1000 corresponds to 100%.
Absolute T1, T2 shows the voltage measured from the A/D converter.
Noise indicates the interference just before the measurement. A typical value is

Timeouts is a cumulative number that indicates how many times the module has not responded to the monitors 
inquiry.
Bad checksums is a cumulative number that indicates how many times communication from the module to the 
monitor has failed. 
Bad c-s by mod is a cumulative number that indicates how many communication errors the module has detected.
The monitor starts counting these items at power up and resets to zero at power off. The non-zero values do not 
indicate a failure, but the continuous counting (more than 5 per second) indicates either a serial communication 
failure, or a module not in place. Also failures in other modules may cause these numbers to rise or be set to 32769.
RAM indicates the state of the RAM memory. 
ROM indicates whether the checksum in the EPROM is in accordance with the software calculated value. 
EEPROM indicates if the values stored in the permanent memory are valid.
The state is either OK, Fail or ? (module not in place or a communication error).

4.8.1 NMT Setup
Start-up is for starting the neuromuscular transmission 
measurement.
Stop/Continue is for stopping/continuing the 
measurement.
Stimulus Mode is for changing the stimulus mode. The 
choices are: TOF - Train of Four, DBS -Double Burst 
Stimulation or ST - Single Twitch mode.
Cycle Time is for changing the time interval for NMT 
measurement. The choices are: 
for TOF and DBS: Manual and from 10 sec to 15 min.
for ST: 1, 10 and 20 sec.
Current is for changing the stimulus current strength. The 
current is either supramaximal (automatic start-up 
search) or manually selected.
Pulse Width is for selecting the desired pulse width. The 
choices are: 100, 200 or 300 µs.

4.9 Oxygen Saturation Modules, E-NSAT, M-NSAT, M-OSAT 
N/OSAT Data
NOTE: Preamp Error is indicated on the service menu, 
even though module contains MP-204 board. 
NOTE: The status and error indicators are not valid for the 
M-OSAT, E-NSAT and the M-NSAT..04 revision.
PR shows the pulse rate value [bpm] calculated from the 
pleth.
SpO
2% shows the oxygen saturation value multiplied by 
100.
Next are listed the messages that are sent from the 
module to the monitor. Digit ‘0’ means that the message 
is not active, ‘1’ is for the active one.
Preamp Error indicates ‘Yes’ if the Preamp (MP-203(4)) 
board detects an error.
QUART Error indicates ‘Yes’ if an error is detected in the 
operation of QUART that is located in the Interface board.
I/O Error indicates ‘Yes’ if an error occurs in the communication between Preamp (MP-203(4)) and Interface board.
Timeouts is a cumulative number that indicates how many times the module has not responded to the monitor’s 
inquiry. 
Bad checksums is a cumulative number that indicates how many times communication from the module to the 
monitor has broken down. 
Bad c-s by mod is a cumulative number that indicates how many communication errors the module has detected.
The monitor starts counting these items at power up and resets to zero at power off. The nonzero values do not 
indicate a failure, but the continuous counting (more than 5 per second) indicates either a serial communication 
failure, or a module not in place. Also failures in other modules may cause these numbers to rise or be set to 32769.
ROM indicates whether the checksum in the EPROM is in accordance with the one the software has calculated. 
The state is either OK, Fail or ? (module not in place or a communication error).

4.11 Interface module, E-INT, M-INT 
Gases, SpO2, NIBP, Spirometry, SvO2/C.O. indicate the 
parameters for which service data is available. The data 
which can be seen on those pages is raw data from the 
interfaced monitors, which will be processed for the 
normal screen.
Service Data
I-INT:  Indicates the status of the interface via the 
UPI section.
B-INT:  Indicates the status of the interface via the 4 
interface channels of B-INT or two channels of E-INT/ 
M-INT module. 
id:  The name of the interfaced  monitor, e.g. Ultima.
state:  describes the state of the connection, alternatives 
are: 
init - the channel is initialized
wait - the monitor is wait ing for the external monitor

search - the external monitor is being searched 
rt:  real time values that are available via the interface.
Timeouts  is a cumulative number that indicates how many ti mes the module has not responded to the monitors 
inquiry.
Bad checksums  is a cumulative number that indicates how many  times communication from the module to the 
monitor has failed. 
Bad c-s by mod  is a cumulative number that indicates how many  communication errors the module has detected.
The monitor starts counting these items at power up and re sets to zero at power off. The nonzero values do not 
indicate a failure, but the continuous  counting (more than 5 per second) indicates either a serial communication 
failure, or a module not in place. Also failures in other  modules may cause these numbers to rise or be set to 32769.
RAM  indicates the state of the RAM memory.
ROM  indicates whether the checksum in the ROM is in  accordance with the software calculated value.
