Bought unit brand new to correct over voltage condition. Wall outlet puts out 125-126 volts. Set switch to 120V, plugged in unit and hit switch. ground fault light is not illuminated. High voltage light illuminates and voltage is stepped down to 110-111 instead of 120. If I set the switch to 110 it steps down to 110-111. If set for 127 it steps to 125 -126. Tried on different outlet and gets the same problem. Tried unit at work before bringing it home. Any ideas?

According to the user's guide here, http://www.apcmedia.com/salestools/ASTE-6Z7V37/ASTE-6Z7V37_R0_EN.pdf, this unit offers a boost of +6% and a trim of -12%. It sounds like it is trimming 12% by my calculations - I don't think it can adjust the trim output to the nominal output voltage (on the switch selector), just trim it 12% based on what the input voltage is.

When you're bumping the selector to 127V, I think it's not really doing anything because you're very close to 127V input so it is not activating boost or trim.

When you set it to 110, I think it is just a coincidence because it is still trimming ~126V down 12% which is ~110V.
