    Why A&D UA-621 Blood Pressure Monitor readings are too high or too low?
    • J
      jeremiahmoyerJul 31, 2025
      Inaccurate readings on your A&D Blood Pressure Monitor can occur for several reasons: * The cuff may not be fastened correctly, so ensure it is properly secured. * Movement during measurement can affect readings, so remain still and quiet. * Incorrect cuff position can also lead to errors; sit comfortably, still and raise your hand so that the cuff is at the same level as your heart. * The device may have difficulty in determining your blood pressure if you have a very weak or irregular heat beat.

    What to do if A&D UA-621 Blood Pressure Monitor cuff does not inflate?

      If the cuff on your A&D Blood Pressure Monitor isn't inflating, it's likely due to low battery voltage. When the LOW BATTERY mark blinks (or if the batteries are completely drained, the mark may not appear), replace all batteries with new ones.

      If nothing appears on the display of your A&D Blood Pressure Monitor, even when powered on, it could be due to drained batteries. Replace all batteries with new ones. Alternatively, the battery terminals might be incorrectly positioned. Reinstall the batteries, ensuring the negative and positive terminals match the indications on the battery compartment.
