How to Take Proper Measurements (1) Preparation before measurement --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. 6 --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 measu- ring; inside a moving vehicle, repeated and contin- uous measuring. (2) Wearing the Cuff Correctly 1) Unroll cuff. Place your arm inside it. (We strong- ly recommend to use your left arm.) 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. 7 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 meas- urement 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 measure- ment. (3) Measurement Tips • To take a measurement, you need to be relaxed and comfortably seated in a room with a comfo- rtable 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 8 your inner arm at the same level as your heart, with the arm resting comfortably on a table. Note: Please use only the manufacturer-provided cuff, as it has passed all required clinical trials. Any replacement of the original components with materials not specified or provided by…
