ALCO-SENSOR FST
sampling system will capture a sample for analysis when either the subject's breath flow begins to decrease or a
second, greater volume threshold is met.
When the sampling system is activated a small sample of deep lung breath is drawn into the fuel cell chamber for
analysis.
If an improper breath sample condition is detected by the instrument, the sample will be rejected and the
instrument will flash "FLO" along with one of the following descriptors: "Lo", "Hi", "InS" or "Cut". (see also: Status
Messages, page 20 for an explanation of the meaning for each of these displayed descriptors.) After this message
is displayed the instrument will return to the ready mode. If the subject is unable to provide a proper sample after
the preset number of attempts the instrument will power itself off. For this reason, it is important for the operator to
provide the subject with clear instruction on how to properly provide a breath sample. (Note: The standard Alco-
Sensor FST will allow the subject three attempts to provide a proper sample before it will display the status
EO6
message and power off.)

Manual Sampling

Manual Sampling is a feature that allows the operator to collect a sample either when the automatic sampling
function has been disabled or the subject is unable to provide the minimum volume of breath. This can occur in
both direct and passive testing modes.
When direct sampling (sampling when a subject blows into a mouthpiece) Manual sampling can produce results
that are as accurate as automatic samples but for best sampling technique, before using this method of testing, the
operator should be trained to collect a manual breath sample. Samples taken too early or after the breath flow has
ceased will result in readings that are lower than the actual deep lung BrACs or BACs.
In the rare occasion when a subject is unable to provide an adequate breath flow to trigger the automatic sample
capture feature, a Manual Sample Capture is possible. This process requires that the operator follow the normal
test procedure up to the point that "bLo" is displayed. At this point the operator should instruct the subject on how
to provide a sample.
As close to the end of the exhalation as possible (but while the subject is still blowing) the operator can collect a
Manual sample by pressing the ON button.
Errors in Manual Testing that must be avoided include capturing a sample before the subject begins blowing;
capturing a sample in the early part of the exhalation or capturing a sample after the exhalation has ceased. In all
of these cases a dilute sample will be drawn into the instrument for analysis and a corresponding low or zero result
will occur.

Note: Certain versions of the Alco-Sensor FST have a pass code or security feature on some menu
functions. If you access a menu function and the instrument does not operate according to the
instructions in this manual, contact your Supervisor. If your Supervisor does not have a pass code key
Intoximeters will need to be contacted.
