15.7 Resetting NIBP
When the pressure does not work properly and the system fails to give a message for the problem,
click on RESET via USER MAINTAIN > NIBP MAINTAIN to activate self-test procedure,
and thus restore the system from abnormal performance.
15.8 Calibrating NIBP
NIBP is not user-calibrated. NIBP pressure transducers must be verified at least once every two
years by a qualified service professional, and calibrated, if necessary. See the Service Manual for
details.
15.9 Leak Test
This item is used for leak test. Turn the knob to pick the LEAK TEST item in the USER
MAINTAIN > NIBP MAINTAIN menu to start the air leakage test. When the item is selected,
it will change into STOP LEAK TEST. If this item is selected again, the system will stop air
leakage test. And the item returns to LEAK TEST. NIBP leak detection should be performed at
least once every two years or when you think the measurement is inaccurate.
WARNING
This pneumatic test other than being specified in the ISO81060-1 standard is to be used
by the user to simply determine whether there are air leaks in the NIBP airway. If at the
end of the test the system gives the prompt that the NIBP airway has air leaks, please
contact the manufacturer for repair.
Procedure of Leak Test
Connect the cuff securely with the socket for NIBP air hole.
Wrap the cuff around the cylinder of an appropriate size. Don’t wrap the cuff around
limbs.
Access USER MAINTAIN > NIBP MAINTAIN.
Turn the knob to the LEAK TEST item and press the item. Then the prompt of Leak
testing… will appear indicating that the system has started performing leak test.
The system will automatically inflate the pneumatic system to about 180 mmHg. After 20
seconds to 40 seconds, if system leakage has detected, the system will automatically open
the deflating valve to stop the leak test and indicates NIBP Leak. If no system leakage is
detected when the pneumatic system is inflated to 180 mmHg, the system will perform a
deflation to an approximate value of 40 mmHg and subsequently perform the second phase
leak test. After 20 seconds to 40 seconds, the system will automatically open the deflating
valve and provide corresponding indication based on the test result.
If the prompt of Leak test over appears, it indicates that the airway is in good situation
and no air leaks exist. However if the alarm information of NIBP AIR LEAK appears,
