4.3 Carrying out an automatic breath test
A new mouthpiece must be inserted for each new person who
provides a breath test.
Do not allow any high alcohol concentrations on the sensor, e.g.
by rinsing the mouth with a high proof alcohol shortly before the
measurement, as this will shorten the service life of the sensor.
1. Remove mouthpiece (order no. 68 10 690 "Standard", 68 11 055
"with back valve")
2. For reasons of hygiene, leave the protective wrapping around the
mouth contact area. Open the packaging at the perforation and
take off the protective wrapping only around the attachment area
of the mouthpiece.
3. Attach the mouthpiece at an angle to the mouthpiece receptacle.
4. Press it into the receptacle. The fluted markings (press-on surface)
on the mouthpiece faces upwards while this is done. The
mouthpiece audibly snaps into place (see page 2).
5. Remove all packaging.
6. Keep the
screen is displayed. An optional self-test is carried out.
7. After approx. 4 seconds the display shows READY and the
instrument is now ready to test. Take a deep breath and blow
evenly and without interruptions into the mouthpiece as long as
possible. A progress bar is displayed. An adequate breath flow is
confirmed by a continuous tone.
8. Without any further action from user side, the device takes
automatically a test sample at the end of the breath of the test
subject.
9. The continuous tone is muted directly afterwards which gives the
signal that the test subject can stop with blowing. The test result is
displayed with date and time after 5 to 25 seconds (depending on
the instrument temperature and the measured concentration).
In case of a negative alcohol test, 0,00 will be displayed.
