The first thing you will notice about the Medisana BU510 blood pressure monitor is the large LCD display. On this display you will find all important information, such as blood pressure values, your heart rate, WHO indicator, memory number, and average measurement. If the BU510 has detected an irregular heartbeat, this will be indicated by a flashing icon. It isn't necessary to write down all readings with pen and paper, since the BU510 has an extensive memory function with as many as 90 memory places per person. In addition, you don't have to work with a calculator, because the BU510 can also calculate the average for you. Are you not very experienced with measuring your blood pressure? The blood pressure monitor gives an error message when the cuff is not properly attached.
