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.

sample cone
moderately hard and
continuously. The
STATUS
light

STATUS
light
will turn
