To prepare the meter for testing:
- Ensure your hands are clean and dry.
- Remove one CareSens N Test Strip from its vial. Close the vial immediately to protect the remaining strips from moisture.

4. Operation: Performing a Blood Glucose Test
Before testing, ensure you have a lancing device and lancets (not included in this meter-only kit, but essential for obtaining a blood sample).
- Prepare Lancing Device: Load a fresh lancet into your lancing device according to its instructions. Adjust the depth setting as needed.
- Obtain Blood Sample: Prick the side of your fingertip with the lancing device. Gently squeeze your finger to form a small drop of blood.
- Apply Blood Sample: Touch the tip of the test strip to the blood drop. The blood will be drawn into the strip automatically. Do not apply blood to the top of the strip.
- Read Results: The meter will count down from 5 seconds and then display your blood glucose result.
- Eject Used Strip: Press the strip ejector button on the meter to safely dispose of the used test strip.
