5. Operating Instructions
5.1 Proper Measurement Technique
For accurate readings, follow these steps:
- Prepare: Sit quietly for 5 minutes before measurement. Avoid talking or moving during the measurement.
- Wrap the Cuff: Wrap the cuff around your bare left upper arm. The bottom edge of the cuff should be about 2 to 3 cm (0.8-1.2 inches) above your elbow. Ensure the air tube runs down the center of your arm.
- Position Arm: Rest your arm on a table or flat surface so that the cuff is at the same level as your heart.
- Start Measurement: Press the START/STOP button. The cuff will inflate, and the measurement will begin automatically. Remain still until the measurement is complete and the results are displayed.
