Question for those who use an Ace 101 spine tester

[slowbowjoe]

So, I've had one of these for a few years. Having an issue with it at times (well actually two) - primarily, sometimes it just doesn't want to zero out for my 11/32" shafts; pressures the arrow before lowering the weight, on any of the 3 height settings, adjusted max high.

What am I doing wrong here?

Oh and the other... I've posted on it a couple years back; the thing consistently reads 4 lbs lowe than actual spine. I can deal with that, but the zero out thing is bugging me.

Any help out there?

Not familiar with the 101 model, might want to call Bob at Ace, If anyone can help, he can.
