• The CGM readings can be calibrated by manually adding a blood glucose entry which is not checked as "Sensor glucose" or "Estimated glucose"
.
• When manually adding blood glucose entries, "Estimated glucose" must be checked ON for all entries, which are retrieved from Freestyle Libre scan or via bluetooth transmitter like BluCon and MiaoMiao.
• On the CGM graph, the calibration points are marked with a red cross. The graph also shows two separate lines - gray and colored. The gray one shows raw values, coming from the sensor, and the colored one shows calibrated values. When the calibration is turned off then the graph shows the raw values only, in a single, thin, colored line.
• The calibration point will take effect and appear on the graph after 15-20 minutes, not immediately.
• Some calibrations might be considered invalid and may not appear at all. If you don't see your last calibration mark after 30 minutes on the graph, then repeat the calibration.
• When adding a calibration point (blood glucose entry), please make sure that your glucose levels are not varying much at the moment. For best results add a calibration entry 2-3 hours after a meal or when you don't have any active insulin in your body.
