At lower heat settings, the output is regulated with pulse induction, where the magnetic fields are turned on and off at regular intervals. The cooktop uses PI technology from German EGO, and this is very normal for the way the induction cooktop controls the temperature. In fact, you will be able to hear when the cooktop pulses, and it will be experienced as if the heat is delivered in intervals. The majority of induction cooktops use this induction technology.
