Dear Buyer, Please Read Carefully Before Using:

1: The first time the instrument is used, people who have not drunk alcohol may also have a reading for the blow test, which is normal, which is caused by the properties of the instrument sensor, and it is recommended that you let the instrument perform a test without blowing before using it.

2: After a period of testing after drinking, the instrument reading is 0, which is normal, indicating that the alcohol has been completely absorbed and decomposed by the human body.

3: It is not recommended that you test immediately after drinking, because the data measured at this time is the alcohol content in the mouth, not the alcohol content in the blood, and the measured data is meaningless.

4: If you drink liquor and other wine with a high reading, there will be a relatively high alcohol concentration in the air near the wine table, and even if you do not drink alcohol, you may have a reading. It is recommended that you test in an open area to get more accurate results.

5: Note on overnight drink: drank a lot of alcohol the night , woke up the next morning to test, the instrument reading is 0 and there are values are normal, this varies from person to person, if the amount of alcohol is good, alcohol has been completely decomposed, the instrument reading is 0; If you drink a lot of alcohol and the alcohol is not completely broken down the next night, then the instrument will measure a reading.
