6. Calibrating the System
This section describes the calibration procedure and schedule of your Eversense E3 CGM System.
To ensure best performance, routine calibration is required using fingerstick readings from a blood glucose meter.
Any commercially available meter may be used for calibration. Once your sensor has been inserted and linked to
your smart transmitter, the system begins a 24-hour Warm-Up Phase. No calibration is required during this phase.
There are three calibration phases:
Initialisation Phase – After the 24-hour Warm-Up Phase, you must complete 4 fingerstick calibration tests,
spaced 2 to 12 hours apart.
2 Daily Calibrations Phase – After the Initialisation Phase, you must complete a fingerstick calibration test every
12 hours for at least 21 days.
1 Daily Calibration Phase – The system will detect if 1 or 2 daily calibrations are needed and will alert you. In the
1 Daily Calibration Phase, you must complete a fingerstick calibration test every 24 hours.
Warning: DO NOT use alternative test sites such as your forearm when entering BG values for calibration.
After the first 21 days, the system will notify you if
1 or 2 daily calibrations are needed.
