Routine Breath Testing
To carry out routine breath testing, follow the simple and clear
instructions on the display.
All test routines ensure that the fuel cell alcohol sensor is clear
before allowing the user to continue. Whilst this is being carried
out the operator is asked to wait.
In active test mode, when prompted to request a sample the
operator should fit a mouthpiece or cup, and ask the subject to
blow. The instrument will automatically detect when a subject is
blowing and will measure the volume of air provided before
automatically taking a sample to ensure that deep-lung air is being
analysed.
Failure to Provide
If the subject does not provide a satisfactory sample then the
instrument will alert the operator to this, and then repeat the
instruction to blow. If the operator does not think that they will be
able to take a satisfactory sample then they are able to record a
failure to provide by selecting the failure to provide button. This
will display a failure to provide screen, and show the number of
attempts. This result will be recorded in the instrument’s database
as a failure to provide.
