c. Press the RECORD key to obtain a printout of the test results.
d. Press the DEFLATE key and then the SELECT key to repeat the Bleed Rate Test, or
press the DEFLATE key to quit the test and return to the NIBP Pneumatic Test Menu.

Leak Test
The purpose of the leak test is to check the leak rate of all the pneumatic components.
a.
Connect the dummy cuff/test chamber to the side panel luer fitting.
NOTE: The dummy cuff/test chamber must be used for this test,
otherwise the test results are invalid.
NOTE: The NIBP hose with a safety leak fitting cannot be used,
otherwise the test results are invalid.
b. Highlight the Leak Test option and press the SELECT key to start the test.
The chamber is inflated to about 200 mmHg. After waiting five seconds for the
pressure to settle, the pressure is noted and then held for one minute. The ending
pressure is noted and then the pressure is released. The current pressure is displayed
in the PRESSURE window during the entire test. The total pressure drop during the
one minute holding period is displayed as the leak rate as shown in Figure 7-6.

d.
Press the DEFLATE key and then the START key to repeat the LEAK TEST, or press the
DEFLATE key to quit the test and return to the NIBP Pneumatic Test Menu.
4. Overpressure Test
The purpose of this test is to determine whether the overpressure sensor is operating
properly. This sensor prevents an overpressure condition in the event that the normal
sensing circuit fails.
a. Connect the dummy cuff/test chamber to the side panel luer fitting.
