Help on the power voltage and PS Premier question


I know I have some problem with my voltage at my home as recently I kept hearing breaking noise from my speaker but all my gears run well in other places. So I borrowed a PS premier to test the voltage. It turns out that the input voltage shows slightly lower than average, 113-4, but the amazing part is during the night, the output voltage only shows 90! and the output THD is jumping bettwen 10-10.5, since PS audio does not suggest the ideal output THD range, does anyone know what does this data means and why the output voltage will drop so much? supposedly PS Premier should keep the output voltage at 120? in the day time it back to normal range 112-115.

I do not live in a house, I lived in an apartment in the city.

Nick, thanks for the information. I did toggled through all the models on the unit so I can get these figures. I think there are problems with the power supply quality of my apartment. I know the PS can default conneting to the wall outlet, but I think the wall outlet is where the problem comes from. My question is, what is the reason causing the high output THD%? is that because of the noise signal from the AC or the surge? how can explain to the power company and ask them to correct the problem? I can not just tell them there are noisy from my speaker, they will think I am nuts.
