Breath Testing Modes Explained
Plus
The FC10 is capable of conducting Automatic, Manual, and Passive tests.
• Automatic Test is the easiest way to achieve a deep lung sample. The FC10
the subject's breath and automatically takes the sample near the end of the breath
fl ow.
• Manual Test is normally used only when the subject is unable to provide a suffi cient
breath sample for the automatic test.
• Passive Test is a quick screen to detect alcohol but is not designed to quantify the
results. Passive results are reported as "POS" if alcohol is detected, "NEG" if alcohol is
not detected. In this mode, no mouthpiece is required.
End of Breath and Precise Volume Explained
In Auto Test mode, the unit can be set to take a sample either:
• When the subject nears the end of the exhalation (End of Breath)
• When it detects 1.5L of breath (Precise Volume)
Both will give accurate results. Precise Volume may work better with uncooperative
subjects.
(To select "END OF BREATH" or "PRECISE VOLUME" mode, see Trigger Mode
instructions on p.14)
