Use

3 3.1   





Use Prerequisites The ambient air must be free from alcohol and solvent vapours (disinfectants). Maintain an adequate distance from mobile telephone antennas and transmitter sites so as not to impair the function of the device. Observe a waiting period of at least 15 minutes after the last oral alcohol intake! Residual alcohol in the mouth can distort the measurement. Even aromatic beverages (e. g. fruit juice), alcoholic mouth sprays, medical juices and drops and, belching and vomiting may result in false data. Also observe a waiting period of at least 15 minutes in these cases. Rinsing the mouth with water or non-alcoholic drinks does not replace the waiting time! The test person should breathe regularly and calmly before the sample is taken. Avoid breathing in and out quickly through the mouth. The test person must be capable of exhaling the minimum breath volume of 1.2 l (works setting). For the test, the breath flow must fall within a certain minimum exhalation time (factory setting 2 seconds). The volume and the time can be changed via the menu, if required.

Alcotest 6820 shut down in 2 sec. 01133400_en.eps

NOTICE The device will switch off automatically approx. 4 minutes after the last use. When the batteries or rechargeable batteries are discharged, the battery symbol flashes and then the device switches off automatically.

Dräger Alcotest 6820

CAUTION Do not allow any high breath 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. Observe a waiting period of at least 15 minutes after the last oral intake of alcohol! NOTICE A new mouthpiece must be inserted for each test subject.

With automatic measurement, the device takes the sample automatically as soon as the test subject has given a breath sample that is sufficient into the mouthpiece of the device and the end of the breath sample has been recognised by the device.

OK
