6. Operation
6.1 Before Measurement
For accurate readings, follow these guidelines:
- Rest for at least 5 minutes before taking a measurement.
- Avoid eating, drinking alcohol, smoking, exercising, or bathing for 30 minutes prior.
- Sit in a comfortable position with your back supported and feet flat on the floor.
- Ensure your arm is resting comfortably on a table at heart level.
- Remove tight-fitting clothing from your upper arm.
6.2 Applying the Arm Cuff
- Insert the air plug into the air jack securely.
- Place the hand through the cuff loop. Pull the cuff until it reaches your upper left arm.
- The bottom edge of the arm cuff should be 2 to 3 cm (0.8-1.2 inches) above the inside elbow.
- Ensure the cuff is wrapped snugly but not too tight. The 'OK' symbol on the screen indicates correct cuff placement.
