Calibration and Battery Indicators

  • Once stabilized, the Eversense Transmitter requires weekly calibrations
    • The Eversense will stop reporting glucose readings if the required calibration is more than 24 hours late
  • The Eversense Transmitter requires charging every 2 to 3 days

The calibration status and battery level is highlighted at the top of the Eversense screen.

Loop Main Screen

When calibration required is within 24 hours, the orange line is echoed on the top of the Loop main screen under the CGM icon to serve as a reminder to calibrate soon.

Once the calibration is due, there is a 24-hour grace period before transmitter stops reporting glucose values. During that time, the "Next calibration in" line is red. This red line is also echoed on the top of the Loop main screen under the CGM icon.

As usual for calibrating a CGM, choose a time when glucose is stable to measure glucose with a finger-stick and enter the value into the user interface. The calibration takes 15 minutes to process.
