Guardian sensor problems

Good morning, I've been with this new meter for a short time
The first 2 weeks were great ... but now I have a difference of about 150 mg/dl between the capillary and the sensor ..
Why can it be?Will I have been wrong?
Thanks for your answers

Hello.I usually put the night before and the active and caliber in mid -morning, when I am more stable.Then I calibrate it before each meal (breakfast, food and dinner).In this way it gives me very tight values.
If you calibrate it when you are having fast variations in glycemia you will give you erroenous values ​​all the time.
It also has to be separated from the cannula insertion zone if you use a pump.

thanks for the information
I will do it that way, because in the last calibrations I was a bit uncontrolled
And I had no choice not to calibrate it at that time ... because it "touched me"

I am very satisfied with the Guardian system.There is almost no difference with the capillary.Of course, calibrate at the time of glycemic stability.Greetings.
