4.2.2 Country wizard
When the instrument is switched on for the first time, a country list opens. After
selecting the required country, the country-specific settings are pre-configured.
Selecting language or measurement unit manually, for example, is then no
longer necessary.
All settings can be retrospectively changed using the menu.
NOTICE
Loss of default settings
If changing the battery takes more than 5 minutes, then the date and time need
to be reset. It is only possible to make a measurement with the time set.
4.3 Taking a breath sample
Use a new mouthpiece for every test person.
Do not apply a high concentration of alcohol to the sensor, e.g. by rinsing
the mouth with high proof alcohol shortly before making the measurement.
This reduces the life span of the sensor.
1. Place new mouthpiece (order no. 83 25 250) on the mouthpiece receptacle
(see page 2).
2. Press and hold the button for approx. 1 second until the startup screen
appears.
3. Approx. 4 seconds later READY is displayed. The instrument is ready to
perform a measurement.
4. Blow evenly and without interruption into the mouthpiece.
When doing so, do not block the outlet opening of the mouthpiece with a
hand.
While doing so, a continuous tone will sound.
After a few seconds (depending on the instrument temperature and on the
concentration measured), the measurement result is displayed.
