My P5 outputs ~119.3V when set to output 120V. Should I set it to output 121, in which case it outputs ~120.3?
Not sure why they are off. Is the meter not calibrated correctly? Shouldn’t the software set voltage to match the meter and your desired setting?
My incoming voltage is usually only 1-4V below 120, so changing the mode to voltage regulation vs distortion reduction doesn’t make a difference.
