]. The NIBP display
shows [

4. After about 20 seconds, the monitor will automatically deflate. This means the test is
completed.
If no message is displayed in the NIBP parameter area, it indicates that the system has no
leakage. If the message [

] is displayed, it indicates that the system
may have a leakage. In this case, check if all connections are good and the cuff and tubing
have no leakage. Perform the test again after making sure all connections are good and the
cuff and tubing have no leakage.
