Passive Mode
For use when the subject is unable to provide a
sufficient sample for automatic sampling, e.g. an
unconscious patient, or for testing the contents of a
container.
NOTE
During the sample process do not move
the device away from the subject until the
sample has been taken. This avoids
allowing fresh air diluting the sample.
3.4 Active Mode Testing
This mode requires the subject to blow
Actively
into
the device. It is the most accurate method of
operation.

STATUS
light

mouth.
•
Tell the subject to blow directly into the
sample cone
moderately hard and
continuously. The
STATUS
light
will turn
AMBER
if the subject is blowing hard enough.
•
Once a correct sample is taken the
STATUS
light
will turn
RED
and an audible alarm
(double beep) will indicate the subject can
stop blowing.
•
Within 5 seconds the result will be displayed
on the
DISPLAY
light
, the colour of the
light indicating the level of alcohol in the
breath sample. The displayed result is
accompanied by an audible alarm giving an
audible indication of the result. (See 3.7)
