Measurement principle
Measuring range
Breath alcohol concentration 0.00 to 2.50 mg/L
Blood alcohol concentration 0.00 to 5.00‰
Indication range
The display is identical to the measuring range.
If the measurement result is out of range, the display will show
three arrows "↑ ↑ ↑" indicating that the measuring range has been
exceeded.

Electrochemical sensor
(Ethanol mass per breath volume at
34 °C and 1013 hPa.)
(Ethanol mass per blood volume
and/or mass at 20 °C and
1013 hPa.
For the above data, a conversion
factor of 2100 is used for breath and
blood alcohol concentration data
(works setting, country-specific
conversion factors can be
configured).
