Interface status indicates the status of the data link 
between the CPU and MEM sections. If the MemCard 
option is installed, the status should always be on 
ACTIVE. If the status blinks between ACTIVE and CLOSED, 
a communications error has occurred.

have been sent (Tx) and received (Rx) since last monitor 
start. Data types are listed on the lines below Message 
types text.
Data types:
Record Kindicates the communication between 
the Monitor and Record Keeper.
File Operationindicates the operations of Patient data.
Serviceindicates the MEM section operations.
Modesindicates the User Mode operations.

1.4 Power supply
The menu shows the voltages and the temperature 
measured by the power management board (PMB 
Voltages) and the main CPU board in the Display 
unit(DU Voltages). The measurement starts about 
100 ms after a start-up. The values in the column 
under Mean are the mean values of the last one 
second, the Min column shows the minimum mean 
value, and the Max column the maximum mean 
value of the voltages and temperature measured 
during the current power ON.
The following voltages are measured by the PMB in 
the Frame Unit:
Raw DC
+15V               14.65….15.35
–15V                -14.65...-15.35 V
+15VD            14.65...16.00 V
+5V                    4.85...5.25 V
Temp (°C) value corresponds with the Frame Unit 
internal temperature measured by the PMB.
The numbers on this page are only directive and not absolute values.
The following voltages are measured by the Central Processing Board in the Display Unit:
+12V                    11.50…12.50V
+3.3V                   3.00…3.60V
VBUS                  10.00…17.00V
Temp (°C) value corresponds with the Display Unit internal temperature measured by the Central Processing 
Board.
MPS input current is the current fed to the Module Power Supply. The current should be

functions.
Upper Led is for testing the upper alarm LED (red) on the 
command board. When the text is highlighted, the upper 
alarm LED can be turned on and off by pressing the 
ComWheel.

Message count counts the number of messages that are sent out to the main CPU board.
Leds upper and lower indicate the states of the alarm LEDs on the command board.
Direct action keys texts are indications to the command board membrane keys. When a key on the command board 
is pressed, the corresponding text in the menu changes its colour.

3.1 Keyboard Log
3.2 Keyboard Type
Keyboard Scroll Log
All the keyboard presses and the commands given 
by the ComWheel are recorded in the Keyboard 
Log. The keyboard log is saved in the permanent 
memory of the monitor. The length of the log is 
1150 events. The log is FIFO type.
Scroll Stat enables to scroll the keyboard events.
Store Mask A selection for the anaesthesia keyboard’s 
language. The selected language determines the 
outcome of the lower keypad.
Store Type is for selecting the keyboard;
COM = Command Board
ARK = Anaesthesia Keyboard
AIC = Information Center Keyboard
NOTE: The settings should be checked if the controller
board is replaced. If settings are changed, the new
settings will not be valid until the next start-up.

4.1.1 General
Service Data
Module configuration shows which measurement 
options are available, i.e. are detected by the module.
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 
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 values may also be reset 
when a module is attached to the monitor frame and be 
set to 32769 or continuous counting may be started when 
the module is removed from the monitor frame. 
The nonzero values do not indicate a failure, but the continuous counting (more than 5 per second) or value 32769 
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.

mV field: signal is scaled to mV.
Gain: User gain. It is scaled as (User gain)/(Factory gain).

ID unrel.*The shown value tells how unreliable the identification is. With pure agent the value is typically < 
75.
Sample Flowis calculated from differential pressure and adjusted by the module. Zero value as measured 
during initialization when the pump is off. Gain: sample flow measurement can be calibrated by 
adjusting the gain. 
Ambient*Ambient pressure is measured continuously in E-miniC. In M-miniC it is measured at least once an 
hour (during the first running hour during each zeroing process). In M-Gas it is measured once an 
hour .

4.1.3 Spirometry
Insp and exp flow gains can be adjusted, if calibration is 
needed. A calibration pump or spirometry tester is used 
and readings are observed from the display. If a deviation 
exists, gains are adjusted accordingly. Gain scaling is 
1.000, when the factory settings are in effect (1.050 in 
modules that contain the Gas Exchange measurement).
When the Adjust key is pressed, a separate box for 
adjusting the value appears. During adjustment 
calibration, values are sent to the module. When the 
ComWheel is pressed, the values are permanently stored 
in EEPROM of the module and the box disappears.
Zero PVX: Start zeroing the pressure sensors. Effects Aw 
Pres Zero and Flow Zero value.
Exp Flow Gain / Insp Flow Gain: Adjust the Flow sensor 
gains.
Valves: Switch between MEASUREMENT and ZEROING
VCO2 / VO2 Gain: Adjust the VCO
2 and VO2 gain.
Y deadspace: Adjust the Y-deadspace.
N2 injection: Select between on (1) and off (0).
Record Data: Record Data prints out the shown service data and board information (id. serial number and software id.) 
onto the recorder module.
