7.
Press the UP ARROW button to display menu item 32.3 in the
SYSTOLIC display. The DIASTOLIC display indicates the rate in mmHg
per second, to the nearest tenth, required to depressurize from 60 to
30 mmHg. A reading of 2.6–4.4 seconds indicates successful completion
of the test.
8.
Return to the service mode steady state by pressing the LOWER ALARM
LIMIT button.
3.3.2.6 High Pressure—Adult
The high-pressure test verifies the functionality of the high-pressure relief
valve in the adult mode. Prior to performing this procedure, the setup
procedure in paragraph 3.3.2 must be completed.
1.
Press the SELECT button on the Bio-Tek simulator until Over Pressure
Test is displayed.
2.
From the N -3100 service mode steady state, press the UP/DOWN
ARROW button until menu item 35 is displayed in the SYSTOLIC
display.
3.
Press and release the UPPER ALARM LIMIT button.
4.
Press and release the START/STOP button. As soon as the N-3100 pump
begins to operate, press the START TEST button on the simulator. The
current pressure in mmHg is displayed in the DIASTOLIC display. The
simulator begins to pressurize until the high-pressure relief valve opens.
If the pressure relief valve does not open by the time 331 mmHg is
reached, the test is unsuccessful.
5.
The SYSTOLIC display indicates menu item 35. The DIASTOLIC
display indicates the maximum pressure achieved. If the high-pressure
relief valve does not open, the DIASTOLIC display flashes. A reading of
330 mmHg or less indicates successful completion of the test.
6.
Return to the service mode steady state by pressing the LOWER ALARM
LIMIT button.
3.3.2.7 High-Pressure—Neonate
The high-pressure test verifies the functionality of the high-pressure relief
valve in the neonate mode. Prior to performing this procedure, the setup
procedure in paragraph 3.3.2 must be completed.
1.
Press the SELECT button on the Bio-Tek simulator until Over Pressure
Test is displayed.
2.
From the service mode steady state, press the UP/DOWN ARROW
buttons until menu item 36 is displayed in the SYSTOLIC display.
3.
Press and release the UPPER ALARM LIMIT button.
4.
Press and release the START/STOP button. As soon as the N-3100 pump
begins to operate, press the START TEST button on the simulator. The
current pressure in mmHg is displayed in the DIASTOLIC display. The
simulator begins to pressurize until the high-pressure relief valve opens.
If the pressure relief valve does not open by the time 166 mmHg is
reached, the test is unsuccessful.
