I'd get an allen wrench and adjust it.
It bothers me slightly that there's a 16 M ohm measurement. But meh.
I'm guessing that the battery is shorter than the distance between the bottom button and the screw and pushing the bottom button activates it. But ....you said something about the switch being in the cap. So....
Anyway...I know you've had enough for now. I have to hit the hay. I wish I had one to envision what's going on. It can't be that much...but it's hard remotely. To me, the cap is where the drip tip goes so I got confused for a bit.
Good luck CES!

That could be bad. They have to know how their meter works.
