6.2 Common factors that lead to erroneous measurements .
Note: Comparative blood pressure measurements should be performed in the
same condition (usually referred to quiet conditions)!

If the arm artery is low (high) relative to the heart , it will result in a high (low)
blood pressure value. (Each 15cm height difference will produce 10 mmHg/1.3
kPa error value)!

This unit is not suitable for newborns.

Note: Please use the original arm cuff that meets the clinical test requirement!

The loose or air bag exposed cuff will lead to false blood pressure.

The arm will compress the blood vessels due to repeated measurements.
This condition will also cause a biased blood pressure value. Therefore, when
making repeated measurements, be sure to rest for 3-5 minutes or raise your
arm for 3 minutes to reduce the congestion.

Do not pressure the cu when measuring, otherwise the measurement will be
inaccurate or out of funcon.
6.3 The correct method of using the cuff:
a. Make sure the arm strap connector is fully inserted into the sphygmomanometer
vent.
b. Please take off your coat, sweater and other thicker clothes, do not have any
accessories, bare upper arm or wear a thin shirt for measurement.
c. Wrap the cuff around the left arm.
d. Do not wrap the cuff too tightly (It is the best to easily insert a finger) and the
lower edge of the cuff should be 2~3 cm
from the hand bend (as shown).
e. After wrapping the cuff around the upper
arm, place the air tube on the inside of the
arm and on the same line as the middle
finger (as shown).
f. When measuring, please sit in the chair, place
your feet flat on the floor, place your arms
on the table, and put the arms and the heart
on the same level to relax and measure in a
relaxed and natural posture.
