Eversense 365 sensor error
A Sensor Check alert, missed calibrations, or a transmitter battery empty for more than 16 hours send the system back to the Initialization Phase. Readings return after new fingerstick calibrations. (Eversense)
What the maker says to do
- Do the 4 fingerstick calibrations the app asks for, 2 to 12 hours apart, within 36 hours.
- Use a blood glucose meter for treatment decisions until readings return.
- Re-link the sensor only if Eversense customer care tells you to.
