The system will always prompt for the number of calibrations per day needed to maintain best system accuracy for each individual user. There is nothing wrong with the system if 2 calibrations/day are needed.
While it is possible, in the Eversense E3 pivotal clinical trial (PROMISE Study), most users were in 1 calibration/day 62% of the time and in 2 calibrations a day 38% of the time, after day 21.
A compatible smart device is required in order to use the Eversense E3 CGM. Please see our Compatibility page for a list of compatible devices.
The system will re-enter Initialization Phase for any one of the following reasons:
- Calibration period has expired without you having entered a fingerstick test value.
- 3 or more blood glucose readings are significantly different than the current sensor glucose readings.
- Y our smart transmitter has not been charged within 16 hours of the empty battery alert.
- If you manually change the time on your mobile device your smart transmitter will sync and reinitialize to your mobile device.
- A new transmitter has been linked to your existing sensor. For example, if you have replaced your existing transmitter.
- If you were instructed by Customer Support to re-link your sensor.
Initialization Phase (after 24-hour Warm-Up Phase)
During the Initialization Phase, four (4) finger stick blood glucose meter tests are required for calibration.
The 4 calibration tests must be spaced 2 to 12 hours apart, and all 4 tests must be completed within a 36 hour period.
– 1st calibration = 24 hours after sensor insertion.
– 2nd calibration = 2 to 12 hours after 1st successful calibration.
– 3rd calibration = 2 to 12 hours after 2nd successful calibration.
– 4th 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.

The Eversense® E3 Continuous Glucose Monitoring (CGM) System is indicated for continually measuring glucose levels for up to 180 days in persons with diabetes age 18 and older. The system is indicated for use to replace fingerstick blood glucose (BG) measurements for diabetes treatment decisions. Fingerstick BG measurements are still required for calibration primarily one time a day after day 21, and when symptoms do not match CGM information or when taking medications of the tetracycline class. The sensor insertion and removal procedures are performed by a health care provider. The Eversense E3 CGM System is a prescription device; patients should talk to their health care provider to learn more.
The Eversense® 365 Continuous Glucose Monitoring (CGM) System is indicated for continually measuring glucose levels for up to one year in people (18 years and older) with diabetes. The system is indicated for use to replace fingerstick blood glucose (BG) measurements for diabetes treatment decisions. Fingerstick BG measurements are required for calibration one time a week after day 13, and when symptoms do not match CGM information or when taking medications of the tetracycline class. The sensor insertion and removal procedures are performed by a health care provider. The Eversense 365 CGM System is a prescription device; patients should talk to their health care provider to learn more.
