relevant OFF message turns to ON.
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 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.
RAM indicates the state of the external RAM memory.
ROM indicates whether the checksum at the EPROM is in accordance with the software calculated value. 
EEPROM indicates if the values stored in the permanent memory are valid.

Service Data
Pressure shows the measured pressure multiplied by 
10. This value is automatically zero-drift compensated.
Zero shows the difference between the zeroing value in 
the permanent memory (stored when the module is 
calibrated) and the current automatic zero-drift 
compensation multiplied by 10. The value can change 
between +20 and -20 mmHg. If the zero drift exceeds ± 
10 mmHg, the module should be recalibrated.
Protect handle indicates hardware protection for 
EEPROM memory. It should be ON all the time in normal 
operation. If it is OFF, data cannot be read from or written 
to EEPROM, only the calibration protection can be set or 
reset by software. It can be turned to OFF by pressing the  
NIBP module buttons Auto ON/OFF and Start Cancel 
simultaneously for 3 seconds, which also enables 
Protection ON/OFF menu selection in the calibration menu.

M-NIBP module and E-PSM(P).
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 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.
RAM indicates the state of the RAM memory. 
ROM indicates whether the checksum in the EPROM is in accordance with the one the software has calculated. 
EEPROM indicates if the values stored in the permanent memory are valid.

4.7.2 NIBP Calibration
How 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. 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: For M-NE(12)STPR series modules: If Protection is ON, change it to OFF by first turning the 
toggle switch to the right at the bottom of the module, which enables the Protection selection. Then 
turn the toggle switch to the left to enable Calibration. When the switch is at the right, 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 the hose from the front panel connector. Select 
Calibration and push the ComWheel. Messages ‘Zeroing’ and ‘Zeroed’ will appear in the NIBP 
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 should be
 
the same as the manometer readings.
Protection: Software calibration protection (ON/OFF). Select OFF when calibrating. Protection selection become
s
available in the menu after pressing the NIBP module buttons Auto ON/OFF and Start/Cancel simultaneously for
3 seconds. For M-NE(12)STPR series modules: Protection can be set ON or OFF only when the toggle switch at the
bottom module is set to the right.

message field. After this, a pressure bar will appear beside 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.
4. When the values are equal, push the ComWheel to confirm the calibration. After a few seconds 
the ‘Calibrated’ message will appear in the NIBP digit field, which means that the calibration 
data has now been saved.
NOTE:  When calibrating NIBP, always change the displayed pressure value slightly with the 
ComWheel, even in cases where the value would be correct. For example, change the value one step 
higher and then back one step lower. The ‘Calibrated’ text should appear in the display. This ensures 
that the calibration procedure is correctly registered and stored by the module.
5. Use the module buttons again to enable Protection setting and set it ON, and finally disable 
Protection setting.
4.7.3 NIBP Safety Valve
Test: Start test is for starting and Stop test is for 
stopping the Safety Valve test.
Safety Valve Data:  
For information on general items Pressure, Zero, 
Protect handle, Calibr. prot., +15 V power, AD0 to AD7 
as well as Timeouts etc., see service data descriptions in 
section “4.7 NIBP Module”.
Max. press and 2 s after stop show the measured 
values at Safety Valve test.
Safety Valve Test Adult/Infant
Wrap an adult cuff around a pipe and connect the cuff to 
the module. Highlight Start test and give the ComWheel 
a push. The test ends automatically or when Stop test 
(appears in place of Start test) is pushed. 
Max. press indicates the pressure at which the safety 
valve opens and is normally 300 ±15 mmHg for adult 
and 150 mmHg ±15 mmHg for infant. 
2 s after stop indicates the pressure at 2 seconds after the pump has stopped and is normally > 270 mmHg for adult 
and > 130 mmHg for infant. If the value is less, check leakage by the active leak test.

4.7.4 NIBP Pulse Valve
How to check Pulse Valve
Wrap an adult cuff around a pipe and connect the cuff to the module. Select Start test and push the 
ComWheel. The pressure rises beyond 240 mmHg and stops. The pulse valve opens. The module 
counts the time it takes for the pressure to go down from 240 mmHg to 50 mmHg and displays it on 
the screen. The test can be manually stopped by selecting Stop test.
The valve can be adjusted between 0 and 255 (0 for fully closed and 255 for fully open). First select 
Set Valve and push the ComWheel. See the pulse valve value and adjust it by turning the ComWheel. 
Then push the ComWheel to confirm the value.
The Interval 240 mmHg -> 50 mmHg time should be less than 60 seconds when the valve is 150 
and less than 10 when fully opened (255). When fully closed (0), the system should be airtight and 
the pressure does not drop. Depending on an individual, the pulse valve may remain closed up to 
approx. value 100.
If the measured time deviates much from those above, then the pulse valve or its tubes are faulty.
Start test is for starting and Stop test is for stopping 
the test.
Set Valve lets you adjust the opening of the pulse 
valve.
