E2: Inflation Error: There is a problem with the inflation of the cuff. Prevention: Ensure that the cuff is wrapped securely and correctly on the arm, and there are no kinks or twists in the tubing
A:AnswerNot sure if the cuff doesn’t have a good fit it might have trouble getting u an accurate reading. I think you can order different sizes. My cuff works fine. Also u might get different readings depending on if u take readings sitting on standing. Hope this helps.
A:AnswerThis sounds like a question for the manufacturer. I have the same problem. Inaddition, I have to continue turning it off and start it over before it will eventually give me a reading.
