Discard Mouthpiece
Remove and discard the mouthpiece in a hygienic manner.
A NEW mouthpiece MUST be used for each complete breath test: but
NOT essentially for repeated blows by a subject in the same test
Wait …. or
Wait for the READY light to come back on [which shows that the
instrument is now clear of any alcohol from the last sample] before
proceeding to test either the same or a different subject. The time
taken for this to occur will depend on how much alcohol was present.
or ….. Switch Off
Switch off manually, or let it to do so automatically after a set time.
4.2 Invalid Breath Samples
If the subject sucks back, blows too gently, or does not blow for long
enough, the ANALYSING light will not come on, so no sample will be
taken for analysis. Depending on the situation, you may allow a
further try, perhaps after re-instruction. There is no need to change
the mouthpiece for repeated blows for the same sample.
4.3 The E2 Message
If E2 is displayed after the ANALYSING light comes on, the breath
alcohol level of alcohol in the breath sample was too high for
accurate measurement. This could be a genuine result, but more
likely it means mouth alcohol was present. The instrument will now
take some time to clear before the READY light comes back on.
