Use: The A&D UA-888 digital automatic tonometer is designed for use as an individual means of monitoring blood pressure and pulse rate. It can also be used for dynamic observations of changes in these parameters in medical institutions. How to take: To measure pressure, you need to put the cuff on your shoulder (preferably on your left arm) so that it is at heart level. After measurement, remove the cuff and turn off the device by briefly pressing the START button. If no operations are performed within one minute, the device automatically turns off. When conducting a series of measurements, the interval between them should be at least three minutes. Contraindications: The A&D UA-888 tonometer operating manual does not list explicit contraindications. However, it is recommended to consult a specialist or attending physician before using the device.
