Preparation of the instrument: If the storage temperature of the blood glucose meter is different from the ambient temperature of the test, it is necessary to balance the instrument and the test strip in the test ambient temperature for more than 30 minutes before testing. There is a temperature sensor near the socket of the blood glucose meter, so do not grasp it when testing.

1. Wash your hands with warm water, dry them, and disinfect the blood collection area with 75% alcohol cotton balls.
2. Open the aluminum foil packaging bag of the test strip or open the test strip bottle and take out the test strip. (The bottle cap should be closed immediately after removing the test strip to prevent moisture. Use within 3 months after opening).
3. Insert the electrical extreme of the test strip into the meter until it emits a prompt sound and the blood drop symbol flashes.
4. Blood collection: Use the blood collection pen at the disinfection site to obtain a sample.
5. Inhalation of blood samples: Touch the top of the test strip to the blood droplet; it will automatically suck into the reaction chamber and start the countdown test.
