In this case, the measured blood glucose value is not accurately calibrated. I have a problem with not being able to In addition, when measuring the reference blood sugar value, if the user's hand is covered with sugar, etc., the reference blood sugar value may be measured with a value different from the actual user's blood sugar value. I have a problem with not being able to.
