I only have the yellow box.

No matter what I do, I cannot zero the thing. The needle goes all the
way to the right to Circuit Check. Does anyone know how to fix that.

I fully realize that the meter has an inappropriate range. So if you

Does it have the separate probe and the little radioactive test patch
