I haven't been able to use the exposure meter on my Pentax K30. I can see it on my lcd display, but it won't move or do anything as I change my aperture or shutter speed. I can't see it at all on my viewfinder. I'm using all manual settings.
Am I missing something obvious?
This is a bit of a long shot, but try dismounting your lens and remount it, making sure it's fully rotated/seated. You could try cleaning the contacts on lens and body to make sure they make proper electrical contact. I just tried partially dismounting the lens on my K-30 and I think I saw similar behaviour.
