Demon Armor and Use Magic Device...

I understand that to emulate an alignment is a DC30 UMD check; however, there is no clear frequency on how often I make that check. Is it when I put the armor on, that I make one check? Or do I make the check every time I make use of its claws? Or is it something completely different?

You make a Use Magic Device check each time you activate a device such as a wand. If you are using the check to emulate an alignment or some other quality in an ongoing manner, you need to make the relevant Use Magic Device check once per hour.

Movin, the PFSRD is not canon. While the folks maintaining the PFSRD are great for doing so they often do not keep up with changes etc. In a rules forum question the PRD should be used instead. However, in this case it is the same text.
