module cuff connector.
Select
Start Pump and press the ComWheel. Check that the pump turns on and the
pressure inside the tubing system starts to increase. Stop the pump by pressing the
ComWheel again when the pressure reaches 280 mmHg.
Highlight
Open Exh2 . Press the ComWheel and check that the pressure inside the tubing
system starts to drop then press the ComWheel again. If necessary, turn the pump on again
for a moment to increase the pressure inside the tubing system.
Highlight
Set Valve . Press the ComWheel and set the value under the text ‘Pulse Valve’ to
number 150 by turning the ComWheel. Press the ComWheel again and check that the
pressure inside the tubing system starts to drop. Finish the test by selecting
Previous Menu .

28. Check the NIBP tubing system for leakages.
Select
Calibrations
from the NIBP service menu.
Connect the pressure manometer to the NIBP module cuff connector. Start the active leak
test from the menu by pressing the ComWheel. The module pumps a pressure of about 265
mmHg and then the pump stops.
Wait for 15 seconds for the pressure to stabilize then check that the pressure does not drop
more than 6 mmHg per one minute. Release the pressure by pressing the ComWheel once
more.
"
29. Calibration check.
Recalibrate the NIBP measurement. Remember to set the calibration protection back on
after the calibration.
Disconnect the pressure manometer. Select
Calibrations and then highlight Calibration
Check . Press the ComWheel and take down the zero offset values for both pressure
transducers, B1 and B2. The values should be within ±20 mmHg.
Connect the pressure manometer to the cuff connector and check the calibration with
pressures 100 mmHg, 200 mmHg and 260 mmHg. The zero offset value must be added to
the displayed pressure value in order to determine the real pressure.
"
30. Check the safety valve.
Select
Safety Valve from the NIBP service menu.
Keep the pressure manometer connected to the cuff connector.
NOTE: Make sure your pressure manometer can be used to measure pressures over 300
mmHg. If such a pressure manometer is not available, perform the check with an adult cuff
that is connected around some round object, for example a calibration gas bottle.
Highlight
Start Test . Start the adult safety valve test by pressing the ComWheel. Wait until
