3.2 Measurement Mode Selection (MAM or single)
Clinical studies demonstrate taking multiple blood pressure readings and calculating an “average” is more likely to
determine your true blood pressure. Your premium blood pressure unit allows you to switch the unit to an Average
Mode setting that automatically takes multiple readings!
Average Mode Slide Switch (MAM):
a) If you would like to take an Average Mode measurement, move the slide switch to
the right.
b) Average Mode takes 3 measurements in succession and calculates the result and
displays it as a single average measurement. A
symbol in the display indicates that the unit is set to the
Average Mode.
c) There will be 15 seconds resting time in-between each measurement. The unit will count down from 15 seconds.
A beep will sound at the last 5 seconds to remind you that the unit is about to take another measurement.
If one
of the measurements causes an error message, it will be repeated one more time. If any additional error occurs the measurement will be
discontinued and error code displayed.
Note: AFIB detection can only be done in MAM mode.
Single mode
a) If you would like to take a single mode measurement, please move the slide
switch to the left.
b) Single mode only has 1 measurement.
3.3 Obtaining Accurate Measurements
Your blood pressure can vary based on numerous factors, physiological conditions, and your surroundings. Follow
these guidelines to obtain accurate and error-free measurements of your blood pressure and pulse rate.

beginning with the measurement. Remain calm and quiet when the measurement is in process. Do not speak
or move your arm (as well as other body) muscles during the process.
3.3B Common Sources of Error
All efforts by the patient to support the arm can increase the blood pressure. Make sure you are in a comfortable,
relaxed position and do not activate any of the muscles in the measurement arm during the measurement. Use a
cushion for support if necessary.
