Functional Verification Procedure
5. Wait another 10 seconds, note the current pressure, and verify that it has not dropped
more than 8 mmHg (1.1 kPa) below the pressure noted in
6. Press several times to select 0 mmHg (0 kPa). The valve opens to release pressure.
7. Disconnect the neonate cuff and replace it with the 500 cc volume test setup.
8. Press once to select 80 mmHg (10.7 kPa). The cuff quickly inflates to approximately 80
mmHg (10.7 kPa), and then settles at a slightly lower pressure level. Wait a few seconds
for the pressure to stabilize.
9. Verify that the value displayed in SYS is within 3 mmHg (0.4 kPa) of the value displayed
on the digital pressure meter.
10. Press to select 150 mmHg (20 kPa) target pressure. The cuff quickly inflates to
approximately 150 mmHg (20 kPa), and then settles at a slightly lower pressure level.
Wait a few seconds for the pressure to stabilize.
11. Verify that the value displayed in SYS is within 3 mmHg (0.4 kPa) of the value on the
digital pressure meter.
12. Press to select 300 mmHg (40 kPa). The cuff quickly inflates to approximately 300
mmHg (40 kPa), and then settles at a slightly lower pressure level. Wait a few seconds for
the pressure to stabilize.
13. Verify that the value displayed in SYS is within 6 mmHg (0.8 kPa) of the value on the
digital pressure meter.
