Belkin PF60 with Monster AVS 2000 issues?

Hi Everyone. I have a question and was hoping someone would be able to help me out. I have a Belkin PF60 and the voltage on the screen says 121.9. I recently received a Monster AVS 2000 voltage stabilizer and I decided to plug in the Belkin PF60 into the AVS2000. After turning the AVS2000 on, it does its magic and stabilizes it to 120v, but for some reason, the display on my Belkin PF60 does not change and stays the same at 121.9v. Am I doing something wrong? Should I be plugging in my stereo equipment into the AVS2000 and not the Belkin PF60?

Any help would be greatly appreciated.
