Calibration Phases
A. Initialization Phase (after 24-hour Warm-Up Phase)
During this phase, 4 fingerstick blood glucose meter tests are required.
• The 4 calibration tests must be spaced 2 to 12 hours apart, and all
4tests must be completed within a 36 hour period.
– 1
st
calibration = 24 hours after sensor insertion.
– 2
nd
calibration = 2 to 12 hours after 1st successful calibration.
– 3
rd
calibration = 2 to 12 hours after 2nd successful calibration.
– 4
th
calibration = 2 to 12 hours after 3rd successful calibration.
• Glucose readings will start displaying in the app a few minutes after
the 2nd calibration is successfully completed.
• When the last several blood glucose meter measurements are
significantly dierent than the sensor glucose values.
• If the smart transmitter is out of battery power for more than 16 hours.
• When you receive a Sensor Check Alert.
• Six hours after you receive a Sensor Suspend Alert.
B. Daily Calibration Phase
The Daily Calibration Phase requires 2 blood glucose meter tests
at the scheduled morning and evening calibration times. The first
Daily Calibration Phase will begin after successful completion of the
Initialization Phase.
• Y our system will automatically tell you when it is time to perform the
twice-daily calibration test.
• Daily Calibration times must be spaced 10 to 14 hours apart.
• The system allows the calibration test to be taken up to 2 hours before
the scheduled time. If you miss your scheduled calibration time, the
system will prompt you hourly.
• The CALIBRATE screen provides the next allowable calibration
time.
Note: If a Daily Calibration test is missed, no additional CGM readings
will be displayed after 16 hours have elapsed since the last accepted
calibration result. If a calibration test result is not entered within
24hours from the last accepted calibration, the system will re-enter the
Initialization Phase.
Re-Entering Initialization Phase
The following will cause the system to re-enter Initialization Phase.
• Not completing a calibration test within a 12-hour period during the
Initialization Phase.
• Not completing all 4 calibration tests within 36 hours during the
Initialization Phase.
• Not completing 2 calibration tests within a 24-hour period during the
Daily Calibration Phase (see C. Daily Calibration Phase).
IMPORTANT: If your smart transmitter is not turned on and
paired with the Eversense App and sensor, the system is not able to
prompt you to calibrate.
