Soundcard calibrating question

[NEP2B]

Hi,

I'm using a Waves DiGiGrid D soundcard.
I wa trying to calibrate the soundcard with the software, but I'm getting a strange measurement if I compare it with Tutorials on Youtube.
What can this be ?

I suspect that you've created a "Feed-Back Loop" ( by having Input Monitoring turned on >> monitoring must be off ) .
