11. Calibration and Service:
Does the tester require calibration? Yes. While some ‘novelty’ breathalyzers cannot be recalibrated, serious
devices such as the tester must and can be recalibrated to ensure consistent accuracy. Consumers should be wary
of units that cannot be calibrated as their accuracy will eventually waver. We provides a calibration service which
can be organized by e-mailing sales@aap.com.hk
12. How often should I re-calibrate the tester or change a new sensor module?
The tester can remain accurate for 1 year of use. The more frequent the use, the more the unit will need to be
calibrated. According to DIN31051, we recommend recalibration every 12 months (or earlier) basis to ensure
maximum accuracy.
Please contact the Authorized service center or reseller to Purchase a Factory
Pre-Calibrated Sensor module or Calibrate your device.
NB* It is important to observe the recommended 15 minute pause without consuming any alcohol, cigarettes or
anything else before testing. Failure to do this can shorten the life of the sensor. In such cases, the sensor can be
permanently damaged or may need more frequent calibration. This user manual should be read carefully for
information on caring for the unit sensor.
Each test change new mouth piece, for best performance, wait for 3 minutes between each test.
Many factors (e.g. environment gas residue, smoke & various smell in human
mouth, etc…) may affect the BAC level, so the readings are For Reference Only.
Neither the reseller nor manufacturer accepts any liability arising from the use
of the unit. Don’t drink before you drive!
