SELECTING THE CORRECT CUFF
Using the correct cuff size is important for an accurate reading. A cuff that is too large will produce a reading that is lower than the correct blood pressure; a cuff that is too small yields a measurement that is higher. With your arm hanging at the side of your body, measure the circumference of your upper arm
at the midpoint between shoulder and elbow.

The air connector is attached to the cuff and inflator bulb tubing. Attach this into the back of the monitor. When changing the cuff size, the exhaust velocity may need to be adjusted (see page 11).
