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 woul d 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.
4.4.3 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 “ 4.4 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.

4.4.4 NIBP Pulse ValveHow 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.

4.4.6 NIBP PneumaticsHow to check Interval 20 mmHg -> 185 mmHg 
Select Start pump  at different combinations of the valves open/closed and push the 
ComWheel. The module counts the time it takes for the pressure to go up from 20 mmHg to 
185 mmHg and displays it. When all the valves are closed, the pump should be able to pump 
the pressure in about 1 to 4 seconds into an adult cuff wrapped around a pipe. The pump does 
not stop without selecting  Stop Pump by pushing the ComWheel.
Start Pump/Stop Pump:  A manual control for the 
pump. The selection changes to  Stop Pump when the 
pump turns on.
Open Exh1/Close Exh1:   This function is not used 
with E-PSM(P) modules.
Open Exh2/Close Exh2:  A manual control for the 
exhaust valve 2. The selection changes to  Close Exh2 
when the valve is opened.
Open Zero valve:  This function is not in use with E-
PSM(P) modules.  
Set Valve:  The opening of the pulse valve is adjusted 
between 0 and 255 (0 for fully  closed and 255 for fully 
open). First push the ComWheel, then turn it to adjust 
the value on the screen and finally push to set the 
value.
Reset Clock  is not in use with E-PSM(P) modules.

5 Set/Test
The power supply unit contains a watchdog 
circuitry, which needs refreshment at every 1.5 
seconds. If the refreshm ent did not occur, the 
watchdog circuitry will re set the main CPU. In 
normal operation, the main CPU refreshes the 
watchdog circuitry at every 0.2 seconds.
The purpose of the watchdog circuitry is to restart 
the monitor, if there was a serious malfunction. 
This feature is useful in two cases: when the main 
CPU is not able to contro l the monitor, or when 
the CPU controls the monitor but detects a 
serious malfunction. Watchdog tests check 
proper functionality of the watchdog circuitry in 
various conditions.
Watchdog  test ensures directly that the 
watchdog of the power unit functions properly. 
Choosing this test prevents the watchdog 
circuitry from refreshing and shows running 
seconds with an accuracy of 0.1 seconds.
The test should have the following result when 
the watchdog circuitry is working properly: The monito r will restart after 1.5 seconds from the start of the 
test. In malfunction: ‘>20 s’ is disp layed, and the test will be interrupted. In this case, the fault is in the 
watchdog circuitry of the power unit.
WD by Overload  test ensures the functionality of a feature,  where the software controls the monitor, but 
detects an overload situation in the main CPU.
The test should have the following re sult when the feature is working properly: The mo nitor will restart after 
15 seconds from the start of the test.
Factory Reset restores the factory default settings and clears the data memories. Factory reset should be 
run if the monitor software is replaced or  if the SRAM/Timekeeper battery is replaced.
