Drinking and driving: Refers to the driving behavior of vehicle drivers whose blood alcohol content is greater than or equal to 20mg/100ml and less than 80mg/100ml.
Drunk driving: refers to the driving behavior where the alcohol content in the blood of the vehicle driver is greater than or equal to 80mg/100ml.

How to use the alcohol tester:

Warm up:

Press and hold the power button for 2 seconds, after a beep, the LCD screen of the tester will be activated.
The “warm up” character appears on the display, and the number counts down from 10 to 00.

Notice:

Since the sensor surface will be oxidized when the tester is not used for a long time, when the tester is taken out of the package for the first time or the tester has not been used for a long time, the user needs to preheat the product as many times as possible before performing the alcohol test.

Test Methods:

After the “preheating” is completed, it enters the “blowing” state, the display shows the blowing character, and the number starts counting down from 10 to 00.
Blow at any time within this countdown. After the machine senses the gas, the machine counts down for 3 seconds, and the buzzer will beep to stop blowing.
Read the test result from the display of the tester.
If the result of the alcohol concentration is 0.00% BAC(or O.Og/I), it means that there is no drunk driving and the green indicator light is on.
If the alcohol concentration is within the display range below the result, the “warning” character will appear on the display, accompanied by a beep, and the yellow indicator light will light up.
Alcohol concentration >0.01% BAC (or 0.1g/l);
The alcohol concentration is less than 0.08% BAC (or 0.8g/I).
If the result of the alcohol concentration is in the following display range, the “Danger” character will appear on the display, accompanied by a rapid beep, and the red indicator light will light up.
The alcohol concentration is >0.08% BAC (or 0.8g/l).

Precautions:

Test after drinking for at least 20 minutes, because it takes about 20 minutes for alcohol to be absorbed from the digestive system into the blood. Immediately after drinking, the results can only reflect the alcohol concentration in the mouth at that time, not the alcohol concentration in the blood.
In order to make the test result accurate, please wait 20 minutes after drinking alcohol before performing the test. The test time is preferably more than 3 minutes from the last test.
Do not directly wipe the product with chemicals or solvents containing corrosive properties to prevent the liquid from flowing into the blowing port.
When there is a high concentration of interfering gas, the machine will not work normally.
If the test is performed under low power, the test valuewill have a certain deviation from the actual value.
It is strictly forbidden to place and use it in a closed environment with corrosive gas or air pollution such as paint, pesticide, alcohol, etc.
Unauthorized repair and damage to internal parts will cause product failure.
Prevent the machine from falling from a high place, squeezing, violent vibration and other dangerous actions.
In order to achieve more accurate test results, it is recommended that users repeat the test 2 to 3 times.

Statement:

Regardless of whether the product is used or not, manufacturers and sellers will not bear any responsibility for illegal activities. For example: drunk driving, working at heights, etc.
Everyone has different reactions to alcohol, so the test results are for reference only and cannot be used as a criterion for determining the results.
