A:AnswerI've had mine checked three times. It is always 10 points higher than my doctors. Either there's something wrong with your doctor's monitor or yours is defective.
A:AnswerThat's because you bought a bad one.
A good home blood pressure monitor, as evaluated by the Cleveland Clinic, should be within ten points of the hospital's readings. Yours is much too far off.
A:AnswerTake it to your doctor and check its readings versus your doctors. I was told my my doctor's nurse you can't calibrate the unit. But by comparing its' reading to your doctor's you'll know how much it deviates. Ten points one way or another is acceptable.
A:AnswerThis is typical. Usually the second reading is lower because your body has adjusted for any stress. If you put the unit on user one it will do an average of three tests with a minute between tests. That's probably to most accurate reading. It will also store the results of the last two hundred average readings. Your manual tells you how to do this.
