The current pressure reading will be displayed until the test is
completed.
6.
Approximately four minutes later, the chamber will depressurize. The
SYSTOLIC display indicates menu item “34.0.” The DIASTOLIC display
indicates the change in pressure from the reference pressure reading
until the end of the 4-minute period, in mmHg.
7.
Return to the service mode steady state by pressing the LOWER ALARM
LIMIT button.
4.3.21 Menu Item 35: Adult Maximum Pump Pressure Test Mode
The adult maximum pump pressure test verifies the functionality of the high
pressure relief valve in the adult mode, and requires a 220 cm
3
test chamber,
a manometer, a manual inflation pump, and an adapter.
1.
Connect the 220 cm
3
test chamber to the N-3100 hose connector.
2.
Using an adapter, connect the manometer and pump in parallel with the
test chamber.
3.
From the service mode steady state, press the UP or DOWN ARROW
buttons until menu item 35 is displayed in the SYSTOLIC display.
4.
Press and release the UPPER ALARM LIMIT button.
5.
Press and release the START/STOP button. The chamber begins to
pressurize to approximately 300 mmHg. The current chamber pressure
in mmHg is displayed in the DIASTOLIC display.
6.
Manually increase the pressure until the pressure relief valve opens.
This normally should happen before the pressure reaches 331 mmHg.
7.
The SYSTOLIC display indicates menu item 35. The DIASTOLIC
display indicates the maximum chamber pressure achieved. If the
pressure relief valve does not open, the DIASTOLIC display flashes.
8.
Return to the service mode steady state by pressing the LOWER ALARM
LIMIT button.
4.3.22 Menu Item 36: Neonate Maximum Pump Pressure Test Mode
The neonate maximum pump pressure test verifies the functionality of the
high-pressure relief valve in the neonate mode, and requires a 220 cm
3
test
chamber, a manometer, a manual inflation pump, and an adapter.
1.
Connect the 220 cm
3
test chamber to the N-3100 hose connector.
2.
Using an adapter, connect the manometer and pump in parallel to the
test chamber.
3.
From the service mode steady state, press the UP or DOWN ARROW
buttons until menu item 36 is displayed in the SYSTOLIC display.
4.
Press and release the UPPER ALARM LIMIT button.
