Adjusting the overpressure requires opening the PRO 100-400
Monitor and adjusting the overpressure potentiometers on the Main
board.
1. Enable Service Mode.
a. Power on the Monitor.
b. Select the More... button from the Main menu.
c. Select the Service button.
d. Enter the Service Mode access code 2 2 1 3 .
e. Select NIBP .
2. Select the Check button. This button sets the overpressure point to
the adult value and closes the pneumatic valves.
3. Adjust potentiometer VR1 fully counter-clockwise.
4. Manually inflate the system pressure to 315 mmHg (the optimal
default Adult Overpressure setting).
5. Once the manometer displays 315 mmHg, adjust VR1 clockwise
until the valves release the pressurized system.
6. Select the Check button again, and verify that the overpressure
trips at 315 mmHg
±
10 mmHg.
7. Select the Pop off button. This button sets the overpressure point
to the neonatal value and closes the pneumatic valves.
8. The unit will display three zeros in the systolic and diastolic
windows.
9. Adjust VR2 (more to the middle of board) fully counter-clockwise.
10. Set the cuff pressure to 157 mmHg
±
2 mmHg using your
connected NIBP test setup.
11. The air pressure within the system may fluctuate initially. Verify
pressure with your external manometer.
12. Adjust VR2 clockwise until the pressure is released and the
Monitor displays Systolic: 000 and Diastolic: 000.
13. Select the Pop off button again, and verify that the overpressure
trips at 315 mmHg
±
10 mmHg.
NOTE: A transducer calibration must be performed after changing the
overpressure thresholds to save the levels into the EEPROM. These
levels are used for a self test during normal operation.
