4.1 Prerequisites for use
The instrument is factory-calibrated when delivered. If the calibration
date is longer ago than 12 months, the instrument should be calibrated,
e.g. by DrägerService. Optional: if the calibration date has been
exceeded, an error message is displayed after the startup screen.
After the last alcohol intake, wait approx. 15 minutes before a
measurement is carried out. Alcohol residues that are still in the mouth
may cause incorrect measuring values. This may also occur due to by
aromatic drinks (e.g. fruit juices), alcoholic mouth sprays, medicines
and drops, as well as by burping and vomiting. Rinsing the mouth with
water or non-alcoholic drinks does not replace the wait time!
