Breathalyzer
ACE A
Important Notes – EN
Each breathalyzer which you buy from ACE Instru-
ments can also be calibrated by ACE Instruments. Of
course, we also calibrate devices which were bought
from other contractors, as long as these devices are
identical in construction to the devices sold by ACE
Instruments.
You can see the due date of the next calibration on
the calibration sticker placed on your breathalyzer. If
the sticker is missing, the calibration is to be done
6 months after the purchase date: e.g. purchase date:
13.05. = next calibration on the 13.11. and the next on the
13.05. of the following year.
For a calibration service you can send the device to
the service address specified at www.alkomat.net.
Why is a calibration necessary?
The calibration is not mandatory, but the accuracy of
the sensor installed in the breathalyzer will decrease
steadily without a calibration and additionally guaran-
tee expires, if you don`t pay attention to the calibration
ranges.
Which factors influence the measurement accuracy
The more often the device is used the more the zero
point is influenced.
The higher the alcohol concentration is, the more the
zero point is relocated.
Devices which are used rarely have a decreased
sensibility, too.

ACE Instruments recommends using the breathalyzer
at least once (1x) a week independently of having
drunken alcohol or not. To maintain the measurement
accuracy, the breathalyzer should also be calibrated
periodically.
