Example: Aeroneb A has an output of 0.25 mL/min and Aeroneb B has an output of 0.20
mL/min when both are run at a 50% duty cycle. The aerosol output of Aeroneb A can be
reduced by modifying its nebulization settings so that both nebulizers produce equal
amounts of aerosol.

Modify the Nebulization duty cycle to the calculated percentage (e.g. 40% in above
example).
4.3 CALIBRATION ACCESSORIES
The importance of proper calibration cannot be overstated. SCIREQ has a number of
accessories used only during calibration steps that may be integrated into your system.
4.3.1 PRESSURE MANOMETER
The SCIREQ pressure manometer is a J-column pressure manometer with a range of 0-300
mmH
2
O. The fluid used with the manometer must have specific gravity = 0.87. The ruler on the
front of the manometer may be adjusted by loosening the silver screws on the ruler and moving
the ruler to the appropriate location. The 0 mmH
2
O mark must correspond with the bottom of
the fluid meniscus when no pressure is applied. Additional fluid may be ordered if needed; refer
to section
1.2.
