11. How to Take Proper Measurements
(1) Preparation before measurement
(2)Wearing the Cuff Correctly
1）Unroll cuff. Place your arm inside it.
(We strongly recommend to use your left arm.)
--Always measure in the same arm (generally the left arm).
--Remain still and keep quiet during measurement.
--Relax as much as possible and do not talk during
measurement.
--Measure your blood pressure at about the same time every
day.
--Do not measure right after physical exercise or a bath. Rest
for 20 to 30 minutes before taking the measurement.
--Readings under the conditions listed below may affect
results:
Within an hour after dinner, after having wine, coffee, tea,
sports; talking, being nervous, being in unsteady mood,
bending forward, moving, room temperature dramatically
changing during measuring; inside a moving vehicle,
repeated and continuous measuring.

(3) Measurement Tips
2）Make sure that the device's screen is positioned on your
inner arm as illustrated in the diagram. The bottom edge of
the cuff should be 0.79-1.18 inches (2 to 3 cm) above the
inside elbow.
3）Tighten the cuff around your arm, so it can not move
around your arm.
Note: Repeated measurement may result in blood
congestion in the arm, which will affect the measurement
result. To avoid this situation, we advise that you can raise the
left hand and hold the fist for several times, or take off the cuff
and rest for at least 2-3 minutes before taking the
measurement.
• To take a measurement, you need to be relaxed and
comfortably seated in a room with a comfortable temperature.
• Sit in a comfortable chair with your back and arm supported.
• Keep your feet flat and
your legs uncrossed.
• The device should be placed
on your inner arm at the same
level as your heart, with the arm
resting comfortably on a table.
