Shows the calibrations made for this sensor. Every calibration consists of the time it was made and the slope (a) and intercept b of the relation between the blood glucose and the sensor glucose:
Blood glucose=a*SensorGlucose+b
When “change slope” is not set in left menu→Settings→Calibration, a=1. So that only b is determined.
Stream: show calibrations of stream values. Stream is the value shown at the moment of the measurement itself and used for alarms and broadcasts.
History: show calibrations of history values (only present on Freestyle Libre and CareSens Air). History values are modified values constructed after the fact as they are displayed in the Librelink and CareSens Air apps.
The display of calibrated curves can be switched on and off in the right middle menu before “Stream” and “History”.
Touching the calibration moves to the calibration time. Touching “Delete” removes the calibration.
Settings: Other way to get to left menu->Settings->Calibration.
