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 co ntinuous 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.

4.2.1 ECG Setup
Filter filters the ECG signal high frequency noise and 
slow respiratory artefacts.
Monit  (monitor) filter is used  in routine monitoring. It 
effectively filters the artefacts caused by the 
electrosurgery unit and respiration. 
Diagn  (diagnostic) filter is used if more accurate 
information of the waveform is needed (e.g. of P-
wave or AV block). The diagnostic filter is more 
susceptible both to high frequencies and baseline 
wander than the monitor filter.
STfilt  (ST filter) permits more accurate information of 
ST segment. It filters the high frequency artefacts 
caused by the electrosurgery unit, but catches the 
slow changes in ST segment. The ST filter is more 
susceptible to baseline wander than the monitor 
filter.
5-lead cable  selects five or three electrodes. With the 
12-lead ECG the selection is automatic. 
Pacemaker  selects how to display the pacing pulse 
of cardiac pacemaker. The selections are  Show, Hide , 
ON R  and Sensit .
Hide , the pacing pulse is filtered away from ECG data.
Show , the pacer pulse is filtered away from ECG data 
but the pulse is displayed as a constant height marker.
ON R , pacing pulses are not filtered away from ECG 
data. This improves ECG monitoring with A-V 
pacemaker patients, as QRS complexes are counted 
even if the pacing pulse hits the QRS complex. 
However, during asystole the monitor may count 
pacing pulses as heart beats. 
Sensit  selection uses a more sensitive pacemaker 
detection. Pacemaker spike is displayed on ECG.

4.4.2 NIBP CalibrationHow to Calibrate
Calibration selection is available only when protection is OFF.  
NOTE: Both channels B1 and B2 must be calibrated simultaneously.
NOTE: The module must be in the frame during the whole procedure.
NIBP calibration can be performed in the NIBP Service menu as follows:
1. If Protection is  ON, change it to OFF  by pressing the NIBP module buttons 
Auto ON/OFF 
and 
Start Cancel simultaneously for 3 seconds, which enables the  Protection selection. 
Select protection OFF in the calibration menu and press the ComWheel. Then press the 
buttons again for 3 seconds to enable Calibration.
NOTE: When the buttons have been pressed, the NIBP field shows an error message 
‘Calibration switch on!’.
NOTE: When calibration is enabled, a message ‘Calibration not protected’ appears.
2. For proper zeroing to take place, remove th e hose from the front panel connector. Select 
Calibration  and push the ComWheel.  Messages ‘Zeroing’ and ‘Zer oed’ will appear in the 
NIBP message field. After this , a pressure bar will appear be side the menu and the text 
‘Calibrating’ will appear in NIBP digit field.
3. Connect an external mercury manometer with  a pump to the module through the both 
tubes of the hose. Pump up to about 200 mmHg pressure (range of 150 to 300 mmHg 
allowed) according to the manometer. Verify that both pressure values in the prompt field 
match the manometer reading. If not, adjust by turning the ComWheel.
Active Leak Test:  Wrap an adult cuff around a pipe 
and connect the cuff to the module. Select the 
active leak test (ON). The module automatically 
pumps a pressure of 260 mmHg into the cuff. Wait 
for several seconds until  the pressure stabilizes. 
Then check that the pressure reading does not drop 
more than 6 mmHg per minute. If it does, leaking 
point(s) should be detected and fixed. Cancel the 
test by selecting the Active leak test OFF.
Calibration Check:  After the calibration check is 
selected (ON), the module zeroes the pressure 
transducers at the beginning of the calibration 
check. Do not pump pressure until the text 
‘Calibrating’ appears in the NIBP digit field or the 
zeroing will fail. After the  zeroing is done, manually 
pump pressure into the module and make sure that 
the same pressure values are shown both on the 
display and on the manometer. Pressure of both 
pressure channels B1 and B2 are shown. The 
pressure values are automatically zero-
compensated, so the readings of B1 and B2 sh ould be the same as the manometer readings.
Protection:  Software calibration protection (ON/OFF). Select 
OFF when calibrating. Protection selection 
becomes available in the menu after pressing the NIBP module buttons 
Auto ON/OFF  and Start/Cancel 
simultaneously for 3 seconds.
