Calipers are special scripted items used by Frans to provide variety to loot lists. It's rather complicated. If you still see them on corpses it's a bug, it means the scripts haven't been able to run properly. I'll be investigating to see if anything can be done about it short of re-writing the leveled list system.
Rather complicated?
Quest script calls quest script calls quest script, and somewhere in there there's a leveled list... what was wrong with just assigning the leveled list in the first place?
Anyway, if anybody is finding naked Fran enemies with a collection of calipers in their inventory, you can fix the problem by opening the console and typing the following:
StopQuest FranLootSet FranLoot.ReSet to 1Set FranLoot.Set to 0Set FranLoot.DoOnce to 0StartQuest FranLoot
This happens, I think, because the FranLoot0Armor quest script doesn't terminate properly, which may be because one of the quest scripts it kicks off doesn't end in time. Resetting FranLoot, which appears to control everything, stops any errant quests and lets the caliper scripts fire off properly.
