Determine the proper arm and inter-arm
difference
If the difference of blood pressure readings between
two arms is more than 20mmHg for Systolic or
10mmHg for Diastolic at all three measurements,
the device indicates the arm with the higher blood
pressure value by displaying L or R and the "IAD" icon.
The "IAD" icon and readings of the higher arm lash to
indicate that more attention is needed.
