Some common reasons for unsuccessful calibrations
Your BG test result is below 60 mg/dL (3.3 mmol/L) or above 300 mg/dL (16.7 mmol/L). Perform the •
calibration test when your blood glucose is within the above range.
Your blood glucose is changing too rapidly. This can happen during a meal or exercise activities or if you
•
have taken insulin. Give yourself an hour before you try to perform a calibration test again. Do not perform
a Blood Glucose mode test for calibration if you do not see the blood drop icon on the screen.
The skin temperature may be out of range (the skin temperature has to be between 77° F (25° C) and 104° F
•
(40° C).
The sensor signal may be out of range or has changed relative to the last successful calibration.
•
Improper Blood Glucose mode testing. Carefully follow the instructions in this Section to perform a BG •
test (keep your hands clean, enter the right strip code and choose finger for calibration tests) to avoid errors
from the Blood Glucose mode test.
The system will prompt you with alarm messages when your calibrations are unsuccessful. See Section 10
for more information or call Customer Care. You will have to perform additional Blood Glucose mode tests
(BG tests) if your calibrations are unsuccessful.
