Top reasons of inaccurate measurements The measurement posture is wrong, the product is not at the same height as the heart When the body is bent and the sitting position is wrong, it is easy to mistake the product\'s cuff to be at the same height as the human heart. Therefore, when the product cuff is higher than the heart, the blood pressure measurement result will be on the low side, and when the product cuff is lower than the heart, the blood pressure measurement result will be on the high side. Talking or moving the body during the measurement The blood pressure measurement technology is the oscillometric method. If you speak or move during the measurement, the cuff and sensor will also detect these interference signals, which will cause the MCU to misread these signals and participate in the algorithm, so the measurement results will be inaccurate. Measurement immediately after exercise or without sitting for 10 minutes before measurement After any exercise, the human body is still in a state of excitement, and the cardiopulmonary function is still in a state of exercise, so the measurement of blood pressure at this time has error and inaccurate. Measured at different times on the same day The blood pressure value of the human body changes in different periods of the day, so the user thinks that the blood pressure value on the same day should be unchanged, so they think the measurement result is inaccurate How to take proper measurements For best accuracy in blood pressure measurement: - Sit comfortably at a table. Rest your wrist on the table - Relax for about 5 to 10 minutes before measurement - Raise your hand so that the wrist cuff is at the same level as your heart - Remain still and keep quiet during the measurement - Do not measure right after physical exercise or a bath - Measure your blood pressure at about the same time every day ! Do not use the device like a hand watch. The display must be on the inner side of your wrist
