On the Calibration
Each breathalyzer which you buy from ACE Instruments can also be calibrated by
ACE. 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.
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 or at www.ace-instruments.net.
Why is a calibration necessary?
The calibration is not mandatory, but the accuracy of the sensor installed in the breat-
halyzer will decrease steadily without a calibration and additionally guarantee 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 inde-
pendently of having drunken alcohol or not. To maintain the measurement accuracy,
the breathalyzer should also be calibrated periodically.
