The operation is very simple and is controlled via once  central button on the device. In addition to the displays of the Alcotest 3820 there are acoustic messages (eg, during breath sample). The device analyzes the breath sample pretty quicky (after about 3 seconds at room temperature or after 10 seconds at high alcohol values ​​<1 per mille = ‰ Promille).

All indications on device status, measurements, firmware / software or error messages appear in clear text on the clear display in German. Audible signals (for example, during the breath sample) complement the display.

The operation runs centrally on one button. Pressing this short, the device turns on and waiting for the breath sample. After Blow (length is given a steady tone during the process) an reslut is issued immediately after a short delay in value in "‰ per mille" ( = blood alcohol concentration). This unit is preset by factory. Unfortunately, you can not change on the device  e.g. in mg / l (= breath alcohol concentration).

The following settings can be made in the menu:

- Measurements (retrieval of the last 10 values)
- Next service (remaining days for calibration)
- Date / time
