breath volume and the minimum blowing
period were reached), the sampling is
triggered. Then the green LED goes out, the
audible signal stops.
The following message appears in the display:

Test Result

After 3 to 20 seconds (dependent on the
detected concentration) the measurement
result appears in the display.
- The measurement result is displayed with
the corresponding unit.
- In the default setting, the unit is set to mg/
L (milligram ethyl alcohol per liter
breathing air) and the solution is set to
two positions after the comma. The
default setting can be changed on the

In addition to the measurement result, an
audible signal which is dependent on the

measurement result below the limit value (PASS) = 1 x,
measurement result between the limit values (ALERT) = 2 x,
measurement result above the limit value (FAIL) = 3 x
40
