Before Taking Measurements: 1. Avoid activity for 5-10 minutes prior to taking measurement. 2. Avoid factors which may affect the reading, including eating, drinking, smoking, exercise and bathing. 3. Always measure on the same wrist (typically your left wrist). 4. Blood pressure fluctuates throughout the day, so be sure to take your blood pressure at the same time each day. 5. Make sure you are in a comfortable, relaxed position, keep the sphygmomanometer in the position of heart. 6. Ensure the cuff is fit snugly around your wrist.
Please Note: 1. Use only with clinically approved cuffs. Sizes can range from 5.3" to 8.5". 2. Damaged cuffs or exposed bladders may affect readings. 3. If put the wrist lower or higher than the heart, a false reading will be obtained. 4. With each reading, blood accumulates in the arm and therefore repeated measurements may lead to incorrect readings. If you need to repeat measurements, be sure that they are spaced 5 minutes apart to avoid error.
