The big peak for the left fringe of the spectrum plot may be the sixty Hz basic. The big harmonic peaks the thing is display that my wall energy below just isn't Tremendous-clean.

CyberPower’s CP900AVR has an uncomplicated-to-use interface with just two buttons (energy on/off and mute) and four indicator lights (exhibiting in the event the unit is turned on, if the battery backup kicks in, when AVR is activated, and when there’s an influence overload) about the entrance with the unit.
