How to obtain a correct posture
Achieving a correct posture before measuring your blood pressure is important since an incorrect
posture might give you incorrect readings. To achieve a correct posture please follow the instructions
(see pictures):
1) Sit down and stretch your back.
2) Relax yourself by relieving the stress from your shoulders and arms.
3) Breath several times deeply and return to natural respiration.
4) Do not sustain your wrist with your other hand and avoid stress in your hand by making firm grips
or large extensions.
Measuring your blood pressure and pulse
If you have achieved the correct posture you can start the measurement. When you measure for the
first time the Position Sensor and the Signal will be ON and measuring at the left wrist will be pre set.
• Push the O/I button to activate your
637IT and the Position Sensor
Screen will be displayed.
