3. Cuff Sizing and Placement
Accurate blood pressure readings depend on using the correct cuff size and proper placement. The UA-651SAC comes with a small cuff designed for upper arm circumferences of 6.3"-9.4" (16-24 cm).
To measure for correct cuff size:
- Allow your arm to hang at your side.
- Locate the midpoint between your elbow and shoulder.
- Measure the circumference of your arm at this midpoint to confirm your fit.
If you require a different size, compatible cuffs (sold separately) include: A&D Medical UA-290A Medium Cuff (9.0-14.6" / 23-37 cm), UA-291A Large Cuff (12.2-17.7" / 31-45cm), and UA-420 Wide Range Cuff (8.6" / 22-42cm).
