Question : How does not changing the code affect readings in a onetouch ultra 2 glucometer?
I’ve read that not changing the code to match the vial with the onetouch ultra glucometer results in inaccurate readings. Why? In what way are the readings inaccurate (too high, too low, every reading is inaccurate or random readings are inaccurate?) Anyone know?
