4. 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.
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 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.
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 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.
9. Verify that the value displayed in SYS is within 6 mmHg (0.8 kPa) of the value on the
digital pressure meter.
Valve and pump current, inflation, and deflation tests
To test pump current
1. Put the monitor in Service mode:
a. Power the monitor off.
b. Power the monitor on while pressing .
2. Press repeatedly until NIBP TEST appears in the message window and 0 is
displayed in the SYS and DIA windows.
3. Press to select 0 mmHg (0 kPa) target pressure.
4. While watching the current meter, press to select 80 mmHg (10.7 kPa) target
pressure.
5. Note the highest current reading during inflation.
6. While the pump is running, verify that the reading on the current meter is not more
than 750 mA above the current level noted in step 2 of the verification test (“Baseline
current draw” on page 13).
7. Press three times to select 0 mmHg (0 kPa) target pressure.
To test inflation
1. Press repeatedly until NIBP TEST appears in the message window and 0 is
displayed in the SYS and DIA windows.
Note
Replace the internal battery with an external power supply. (See “Battery
substitution cable setup” on page 12.)
WARNING Do not connect the monitor to a patient while the monitor is in
Service mode. Overpressure detection is disabled while the monitor is in NIBP
test mode.
