The induction hob "beeps, sizzles, pulsates"

Hello,

I bought an induction hob as in the subject, connected to two phases.

The hob works on the pulse principle - on / off - at different times depending on the heating level.

Furious wife - the previous induction worked without pulsation, only "continuously" - in the store / manual / google I did not find information about it, only the lady from the Beko hotline said "this guy does" ...

War at home... This is not how to cook!!! ...

Is there any possibility / method of recognizing whether a given hob cooks in pulses or continuously?

I have the same problem, I bought Beko and if I set two burners in one vertical, it cooks pulsatingly. If I put one on the left and one on the right, it cooks normally, these Beko kitchens have it, not from this series. I reported it and was told that these types are like that and the manual says that if you turn on two fields in one line, then you cook one time the other alternately. It's people's deception
