- Wrap the cuff around your bare upper left arm, about 1-2 cm (0.4-0.8 inches) above the elbow joint.
- Ensure the air tube is positioned along the center of your arm, aligned with your middle finger.
- The cuff should be snug but not too tight; you should be able to fit one finger between your arm and the cuff.
