Calibration is generally not required as the sensor is factory-calibrated. However, if you notice a significant difference between your sensor and blood glucose meter readings, you may calibrate the sensor. Avoid calibrating more than once per day and wait until your glucose levels are stable.

Do not calibrate within the first six hours after sensor installation or when your glucose levels are rapidly rising or falling. Ensure that your glucose levels have stabilized before performing a calibration.

If the difference is greater than 20 mg/dL for readings below 80 mg/dL or more than 20% for readings above 80 mg/dL, you can use the calibration option in the LinX app. Contact customer support if you need assistance.

Calibration adjusts the sensor readings to match your blood glucose meter, and it will be marked with a red dot on the trend curve. Recording simply logs the blood glucose measurement without adjusting the sensor and is marked with a green dot.

CGM sensors measure glucose in the interstitial fluid under the skin, while blood glucose meters measure glucose directly in the bloodstream. This difference, known as lag time, can cause slight variations between the two measurements.

You can perform calibration yourself through the LinX app. However, if you are unsure about the process or if you are new to using LinX , it is advisable to contact customer support for guidance.
