Q: Why was my calibration rejected?
A: The system will reject the calibration for the any of
the following reasons:
• The blood glucose reading entered is less than
2.2 mmol/L.
• The blood glucose reading entered is greater than
22.2 mmol/L.
• The blood glucose reading entered is significantly
dierent from the last sensor glucose reading.
If the calibration is rejected, you must re-calibrate.
You may need to wait up to 60 minutes before
re-calibrating.
Q: Can I calibrate earlier than my scheduled time?
A: You can calibrate up to 2 hours before the scheduled
time. If you miss your scheduled time, the system will
send an hourly calibration prompt. To view the next
available calibration time, tap Menu > Calibrate.
The next scheduled calibration time is displayed.
Q: What time should I enter on the CALIBRATE
screen when I am notified to calibrate?
A: Enter the time you tested your blood glucose with
your meter. You must enter the blood glucose reading
within 10 minutes of doing the test.
Q: Where can I find details for Calibration Phase,
number of calibrations and last calibration date
and time?
A: You can view calibration details by tapping Menu >
About > My Transmitter.
Q: What are the dierent types of calibration phases?
A: The Eversense XL CGM System has two types of
Calibration Phases, the Initialisation Phase and the
Daily Calibration Phase. Initialisation Phase begins
24 hours after sensor insertion and requires
4 fingerstick blood glucose tests for calibration. The
Daily Calibration Phase occurs after the Initialisation
Phase and requires 2 daily calibrations (morning and
evening) for the life of the sensor.
