What does Calibration Not Used mean?

The calibration not used alert means that the sensor was unable to use the calibration you entered.
If you see this message, give your sensor some time to adjust; then, try calibrating again in about an hour with a new fingerstick. To get an accurate BG meter value, follow these steps:
  1. Wash your hands with soap and water.
  2. Dry your hands
  3. Take a fingerprick
