Precautions
1. Test at least 20 minutes after drinking, because it takes about 20 minutes for alcohol to be absorbed from the digestive system into the blood. If tested immediately after drinking, the result can only reflect the alcohol concentration in the mouth at that time, not the alcohol concentration contained in the blood
2. For accurate test results, please wait 20 minutes after drinking before testing, and the test time should be more than 3 minutes from the last test
3. Do not wipe the product directly with chemicals or corrosive solvents to prevent liquid from flowing into the air blow pipe
4. The machine will not work properly when there is a high concentration of interfering gas
5. If the test is performed at low voltage, there will be a certain deviation between the test value and the actual value
6. It is strictly forbidden to place and use it in a closed environment with corrosive gases such as pigments, pesticides, alcohol, or polluted air
7. Unauthorized repair and damage to internal parts will cause product failure
8. Prevent the machine from falling from a high place or being subjected to severe vibration
