If you think your sensor is creating a line that's higher than it ought to be, you can move it down by calibrating.
How to calibrate
Do this first thing in the morning, in the fasted state, before you’ve had any nutrition or done any exercise.
- Go to the profile screen (person icon)
- Scroll to find the Aidex sensor
- Press blue calibrate button
- Type in 5.5 (right in the middle of the WHO’s recommended range)
- Press yellow calibrate button
Here’s a video that shows you how to do it.
