4. Press
approximately 80 mmHg (10.7 kPa), and then settles at a slightly lower pressure level.
Wait a few seconds for the pressure to stabilize.
5. Verify that the value displayed in SYS is within 3 mmHg (0.4 kPa) of the value
displayed on the digital pressure meter.
6. Press
approximately 150 mmHg (20 kPa), and then settles at a slightly lower pressure level.
Wait a few seconds for the pressure to stabilize.
7. Verify that the value displayed in SYS is within 3 mmHg (0.4 kPa) of the value on the
digital pressure meter.
8. Press
mmHg (40 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 6 mmHg (0.8 kPa) of the value on the
digital pressure meter.
