IMPORTANT NOTES ON THE CALIBRATION
Each breathalyzer which you buy from ACE Instruments 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 at latest
12 months after the purchase date: e.g. purchase date: 13.05. = next calibration on the
13. 1 1. 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.ace-technik.com.
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.
