I put a 2200uF electrolytic cap in my tester and it measured the ESR of that. I don't think the ESR test works for caps in the pF range.

Works fine here... It's just a picture of a film cap that says 330J and S50F.

317pF. Again, the formula is [first two digits] multiplied by 10 to the power of [third digit]. 10 to the power of 0 is just 10 so 33 x 10 = 330 (which is the full three digits anyways). If it was 33pF, why wouldn't they just save ink and write only "33"?
