  If your LifeSource Blood Pressure Monitor unit isn't measuring correctly, and the readings appear too high or too low, consider these possible causes: * Ensure the cuff is fastened correctly. * Remain still and quiet during the measurement if you moved your arm or body. * Sit comfortably and ensure the cuff is at the same level as your heart if the cuff position is not correct. * Relax for five minutes before each measurement, especially if you're taking multiple readings in a short period.
