The calibration routine consists of two steps:
After a warm-up time of 1 hour, the sensor is in Trend Mode, and sends CGM values to the app every 5 minutes. Don't use these initial CGM values to make therapy decisions, such as insulin dosing. 12 hours after insertion of the sensor, the app prompts you to calibrate.
Step 1: Perform a blood glucose test and enter the glucose value into the app. The sensor goes into Therapy Mode. CGM values can now be used to make therapy decisions, such as insulin dosing.
Step 2: 30 minutes to 3 hours later, when prompted, perform another blood glucose test and enter the glucose value into the app. This is to confirm the first measurement. Note: If step 2 is missed, the sensor returns to Trend Mode.
The calibration routine is completed for the sensor.
To calibrate your sensor:
1. Test your blood glucose with your blood glucose meter, according to the manufacturer's instructions.
2. Tap Calibrate Now on your Home screen.
3. Enter the glucose value from your blood glucose meter on the Calibrate CGM sensor screen. The glucose value should be entered no later than 3 minutes after performing the test.
4. Confirm that you understand that you can’t edit or delete calibration values once they are confirmed and tap I understand.
5. Check that you entered the same glucose value into the app that was displayed on your blood glucose meter and tap Confirm. If you accidentally entered an incorrect value, tap Keep editing and enter the correct value.
The glucose measurements of the sensor are more accurate if you calibrate at a point in time when your blood sugar level is relatively stable. Do not calibrate shortly after a meal, after insulin administration, or after physical activity, and avoid environments with very hot or very cold temperatures, or rapidly changing temperatures. If you accidentally entered an incorrect value, tap Cancel and enter the correct value.
Your sensor is calibrated.
