When the pressure pump does not work properly and the system fails to give message for the
problem, pick this item to activate self-test procedure, thus restore the system from abnormal
performance.
Leak Test
This item is used for air leakage test. Press this item to start the air leakage test. Then the item
will change into Stop Leakage Test. If it is picked again, the system will stop air leakage test.
This leakage test other than being specified in the ISO 81060-1 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 the Air Leakage Test:
1) Connect the cuff securely with the socket for NIBP air hole.
2) Wrap the cuff around the cylinder of an appropriate size.
3) Access the NIBP Setup menu.
4) Select the Leakage Test item by pressing the UP/DOWN button. It displays indicates
Leakage Test on the bottom of the parameter area.
5) 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 AIR 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.
6) If no prompt appears on the bottom of the NIBP parameter area, it indicates that the
airway is in good status and no air leaks exist. However if the prompt AIR LEAK
appears in the place, it indicates that the airway may have air leaks. In this case, the user
should check for loose connection. After confirming secure connections, the user should
re-perform the pneumatic test. If the failure prompt still appears, please contact the
manufacturer for repair.
