the USB spirometer sensor and are not editable fields. The
temperature must be 10°– 40° C, 50°–104° F. The
atmospheric pressure must be 600 –1100 mbar, 450 – 825
mmHg, 18 – 32 inHg, 60 – 110 kPa.

the flow transducer all the way in for a tight seal.
7. Touch the Continue button.
CAUTION Several things may affect calibration results:
movement of the syringe, movement of the pressure tubing,
or blockage of air. Place the syringe on a hard, level surface
with at least 1 cubic meter of open air surrounding the flow

movement.
8. Touch the Start button to begin the calibration.
9. When the black bar begins to move, push the plunger all the way in, then pull it all
