Open Exh2 Opens exhaust valve 2; changes to Close Exh2 when the valve is open. 
Set Valve Adjusts the pulse-valve opening between 0 (fully closed) and 255 (fully open). To 
adjust, push the ComWheel, turn it to adjust the value shown on the screen, and 
push it to set the value.

Exh1 Valve and Exh2 Valve show the states of exhaust valve 1 and exhaust valve 2 (OPEN/CLOSED). 
Pulse Valve shows how much the valve is opened (0 to 255) during Valve Setting. 
Watchdog BEEP check 
Connect a manometer to the front panel and pump in pressure. When the AD5 value changes from a 
negative value to a positive value (at about 15 mmHg/2.0 kPa), a beep sounds. This is the watchdog 
threshold pressure. Beyond this pressure the watchdog is active and cuts pressure at about 2 minutes 
(adult).

After the current value, the test status is shown.  
 If the test is not passed, factory calibration is needed.  Contact GE Healthcare. 
T1%/ref  NMT MechanoSensor setting. Always use a setting of 3 for normal monitoring. 
Settings 1 and 2 are for research purposes only. 
Record Data Prints the displayed service data and circuit board information (id., serial number, 
and software id.) to the optional Recorder. 
NMT Service Data screen 
Cable The type of cable being used. 
Cable check value The bit amount. You can check the value for each cable using this chart:

Service Menus 
T1%, etc. The measured response. A value of 1000 corresponds to 100%. Each is a ratio of 
the Absolute T1, etc. to the Reference (Ref). As drugs are administered, the 
typical response for T1 lessens, then drops more rapidly for each successive 
measured response (T2%, T3%, then T4%).  
Ratio% The common label for TOF/DBS%.  
Absolute T1, etc. The voltage measured from the A/D converter. The area-under-the-curve of the 
response to stimulation as the muscle-relaxant anesthetic is being administered. 
Ref (Reference) The area-under-the-curve calculation from the response of the NMT 
stimulation before the administration of inhibiting anesthetics.  
Noise The interference just before the measurement. A typical value is < 10. Represents 
the measurement of the area-under-the-curve of the response when no stimulus 
is given, but the circuitry noise is picking up some response. The noise factor 
varies from sensor to sensor. 
Offset An average of the noise measurement; the voltage baseline. An offset of 2520 is 
2520 mV, or 2.5 V.  This is the measureable baseline voltage of the sensor and 
varies from sensor to sensor.  
Curr set The selected current, a value of 700 corresponds to 70 mA. 
Curr meas The measured current, a value of 700 corresponds to 70 mA. 
Pulses Pulses the module has produced. 
Piezo probe T1% Information related to MechanoSensor settings. 
Ref. search Information related to MechanoSensor settings. 
Timeouts, Bad checksums, and Bad c-s by mod are cumulative numbers that indicate the following: 
Timeouts—how many times the NMT unit did not respond to an inquiry from the 
monitor. 
Bad checksums—how many times communication from the NMT unit to the 
monitor failed. 
Bad c-s by mod—how many communication errors the NMT unit detected. 
Counting starts at power on and is reset to zero at power off. Nonzero values do 
not indicate a failure, but continuous counting (more than 50 per second) 
indicates a serial communication failure or that the NMT unit is not installed. Also, 
communicaton errors from other modules can cause these numbers to rise. 
RAM The state of RAM memory.  
ROM Indicates whether the checksum in the EPROM is in accordance with the value 
calculated by the software.  
EEPROM Indicates if the values stored in permanent memory are valid. The state is either 
OK, Fail or ? (module not installed or a communication error).

To access this menu from the Service View menu: 
1. Select Modules. 
2. Select NMT. 
3. Select NMT Setup. 
 
Start-up Starts an NMT measurement. 
Continue Continues an NMT measurement. 
Stimulus Mode Selects the mode of stimulation:  TOF (train of four), DBS (double burst 
stimulation), or ST (single twitch). 
Cycle Time Sets the time intervals for the selected Stimulus Mode. For TOF and DBS, the 
selections are Manual, 10, 12, 15, or 20 seconds, and 1, 5, or 15 minutes. The 
ST cycle times are 1, 10, and 20 seconds. 
When the cycle time is less than one minute, the Count must be below the Count 
limit in two successive measurements before the Recovery Note is enabled. To 
give the note, the number of Counts must exceed or match the limit twice in one 
minute. The note disappears when two measurements are below the limit again. 
If the cycle time is one minute or more, or if the measurement is done manually, 
at least one Count must be below the chosen limit before the Recovery Note is 
enabled. To give the note, one Count must exceed or match the Count limit. The 
note disappears when one measurement is below the limit again. 
Current Sets the stimulus current, which is either supramaximal (automatic start-up 
search) or manually selected from 10 mA through 70 mA at 5 mA intervals. 
Pulse Width Increases or decreases the effect of the stimulation. Selections are 100 µs,  
200 µs, and 300 µs.

monitor failed. 
Bad c-s by mod—number of communication errors detected by the SpO2 unit. 
Counting starts at power on and is reset to zero at power off. Nonzero values do not 
indicate a failure, but continuous counting (> 50 per second) indicates a serial 
communication failure or that the SpO2 unit is not installed. Also, communicaton 
errors from other modules can cause these numbers to rise.
