If the subject blows properly, but then sucks
back just as the breath sample is taken for
analysis, the following message appears:
There is no alcohol reading, and after a short pause the screen
invites a further attempt. If you wish to offer the subject one, it is
advisable to re-instruct them to blow properly, without sucking back:
If the subject sucks back when the analysis is underway [ie after the
Sample Taken message has appeared] then there is no effect on the
alcohol measurement, so the alcohol reading will be given as normal.
NOTE: you do NOT have to change the mouthpiece for repeated
attempts by the same subject in the same test procedure.
If the subject refuses to blow into the instrument, or by his actions
and perhaps after one or more ‘attempts’ at blowing into it it is clear
that he or she is not going to provide a proper specimen, then you
may terminate the procedure by logging a refusal. To do this press
and continue to hold down the small button [FSA] until the beeper
sounds and the screen shows a message such as the following:
The number in the above screens is a record of how many detectable
but insufficient blows the subject made into the device.
