Important
To begin, rinse your mouth with fresh water before using the device. Abstain from smoking or drinking for at least 15 minutes. If you perform a test just after drinking, the reading will fluctuate from very high to low reading, i.e. it will drop gradually. It is due to the alcohol residues inside your mouth that effects the test values. This will also happen with aromatic drinks, alcoholic mouthwashes or mouth sprays, medicines or drug, as well as by burping and vomiting.
Also, when alcohol enters the blood through the alimentary canal (mouth, stomach, and intestines), it is distributed through every part of the body, including the lungs. This period will last for about 15~30 minutes before stable. Our device detects human breath and gives a digital reading out of a person's approximate Blood Alcohol Concentration (known from here on as BAC). If user direct blow very high concentration into the sensor, its surface will be surrounded by lots of ethanol particles, which need to wait for 10 min for evaporation.
Time from stable to zero: It takes from few minutes to few hours, depending on the amount of alcohol you drink, your physical condition and the detoxification function of your liver. In fact, detoxification capacity is an important factor. in the concentration test.
Most people think that it should still give a high value after 1 or 2 hours, but this is definitely wrong. The tester will only show the actual concentration detected in your lungs, which varies from person to person. In fact, for <0.05%BAC, most drop to low levels after 1-2 hours (especially if you drink regularly)
(1) After any 4 consecutive tests, please allow the device to rest for 2 minutes.
(2) When low battery indicator flashes, the reading is invalid, please recharge the battery immediately.
(3) If the difference between two successive reading is >0.01%, usershould test again.
(4) If there is very high concentration tested, user should wait for at least 3 min to perform another test.
