Using the Monitor
Applying the arm cuff
1. Wrap the cuff around the upper arm, about 0.5" (1-2 cm) above the
inside of the elbow, as shown.
Place the cuff directly against the skin, as clothing may cause a faint
pulse and result in a measurement error.
2. Constriction of the upper arm, caused by rolling up a shirtsleeve,
may prevent accurate readings.
3. Confirm that the index p points within the proper fit range.
Note: During measurement, it is normal for the cuff to feel very tight. (Do not be alarmed).
