First ensure that no drugs, alcohol, tobacco or spicy food was consumed for at least 30 minutes before taking a reading. While relaxed, place yourself at a table, with the feet flat upon the ground, legs uncrossed, and a straight back.
Place your elbow on the table, and lift the wrist to heart level, facing away from your body at around 30-45 degrees. The cuff must be wrapped as per manufacturer specifications and the screen facing you. Push the on/off button and wait calmly as the cuff inflates then deflates for the machine to take its reading.
