CALIBRATION
•
The precision of alcohol level testers may change after 6-12
months of use, depending on the number of tests and working
conditions.
•
If the device shows inconsistent test results, fails to show
any results or displays very high or very low results, it must
be calibrated.
•
To perform calibration, please contact the service center.
