Directions for Use Chapter 3 Calibrating the Spirometer 27
If desired, you can press Stop any time. Softkeys will change, as described in Step 11
on page 28.
Otherwise, when no air has moved for three seconds, the following happens:
For verifications or single-flow calibrations
The results display.
For multiple-flow calibrations
Another simulated exhalation screen appears. Repeat from Step 8 twice more.
The results display.
10. Review your results.
Check the error percentages for the expired and inspired volumes. Both/all must be
less than ±3% for your calibration to be acceptable. For single-flow calibrations, the
measured and adjusted curves should match. See the following examples.
