The exhaled breath volume is indicated via a sample progress bar; scrolling left to
right at the bottom of the screen and a graph showing air flow over time in
seconds (Refer Figure 9).
A beeping sound is also heard during the breath sample delivery phase, indicating a
satisfactory breath sample is being delivered.
Figure 9- Sample Progress Bar
The test subject continues blowing until the instrument takes a sample of
the exhaled breath volume, indicated by a click and long beep sound.
The frequency of the sound beeps increases with the intensity of the blow pressure. Blowing too
hard or too soft will result in ‘Invalid Sample Try Again’ being displayed (Refer Figure 10). The deice
will return to the Blow screen for another sample to be taken.
