Calibration Phases
A. Initialisation 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.
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.
Re-Entering Initialisation Phase
The following will cause the system to re-enter Initialisation Phase.
• Not completing a calibration test within a 12-hour period during the Initialisation Phase.
• Not completing all 4 calibration tests within 36 hours during the Initialisation Phase.
• Not completing 2 calibration tests within a 24-hour period during the Daily Calibration Phase
(see B. Daily Calibration Phase).
• 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.
