Product operation steps:

1. Install the battery and turn it on, the screen will display the setting date and time screen, use the left button to adjust the number (click Add. Long press to decrease), right-click. If you remove the battery, the time is left for about three minutes at most, after which you need to reset the time at the next reboot.

2. After booting, the current time will be displayed in the middle of the screen, and if the Bluetooth is successfully connected, the symbol (undefined) will be displayed

3. Turn on the Bluetooth printer first, and turn on the tester (reverse operation will make the connection successful time longer) colleagues to ensure that there can be no other Bluetooth devices around.

4. After the results appear after each test, right-click to print the current test results.

Notes:

1. Test after drinking alcohol for at least 20 minutes, because it takes about 20 minutes for alcohol to be absorbed from the digestive system into the bloodstream. Tested immediately after drinking, the results only reflect the concentration of alcohol in the mouth at that time, not the concentration of alcohol contained in the blood.

2. In order to make the test results accurate, please wait 20 minutes after drinking alcohol before testing, and the test time is preferably more than 3 minutes from the last test.

3. Smoking and eating are strictly prohibited within 20 minutes before the test.

4. Do not directly wipe the product with chemicals or corrosive dissolved liquid to avoid liquid flowing into the blowing pipe.

5. If the test is carried out under low power, there will be a certain deviation between the test value and the real value.

6. It is strictly forbidden to place and use in a closed environment with corrosive gases such as pigments, pesticides, alcohol or air pollution.

7. Unauthorized repair and damage of internal spare parts will lead to product failure.

Postscript:

Criteria for drinking and driving drunk: the driver's blood alcohol content greater than or equal to 20mg/100ml, less than 80mg/100ml is drinking driving, and the alcohol content greater than or equal to 80mg/100ml is drunk driving.  

Under normal circumstances, if you just drink alcohol, immediately take a breathalyzer test, the value may be relatively high, but after 20~30 minutes of testing, the value may decrease, but this value is more accurate, because the alcohol has entered the blood through digestion and absorption. Although the threshold for traffic police to penalize drunk driving is 20mg (or 0.02g), this does not mean that it is safe to drive below 20mg (or 0.02g).

Theoretically, after a person drinks 350ml (about 1 small bottle) of beer or half a liquor (20ml), the blood alcohol concentration can reach 20mg/100ml; When the amount of alcohol consumption rises to 1400ml (about equivalent to 3 bottles of 500ml) beer or one or two halves of liquor (80ml), the blood alcohol concentration can reach 80mg/100ml. This data is somewhat different from the actual test results, because the human body has different ability to absorb and decompose alcohol. The same glass of wine, one person may not feel at all when he drinks it, while another person may drink it, he may be drunk.

According to the report of the World Health Organization, when the blood alcohol content of the driver reaches 80mg/100ml, that is, the threshold of drunk driving, the chance of a traffic accident is 2.5 times that of the blood without alcohol. With a blood alcohol content of 100mg/100ml, the chance of a traffic accident is 4.7 times higher than when there is no alcohol in the blood. Even when drinking a small amount of alcohol, the risk of a traffic accident can reach about twice that of the unconsumed state.

Statement:

1. Regardless of whether the product is used or not, the manufacturer and seller will not bear any responsibility for illegal acts. For example: drunk driving, working at height.

2. Each person's reaction to alcohol is different, so the test results are for reference only and cannot be used as a standard for determining the results.
