Doesn't the Klein schematic show something about a lower voltage (like 10V
maybe)? I say split the difference with a voltage divider (didn't I put
something about this in there too)? Take one 100K resistor and put one side
at 15V and on the other side place 1) a second 100K resistor, and 2) an
OUTPUT. Connect the other side of the second 100K resistor to ground. The
OUTPUT should be about 7.5V. I know I put some stuff about scaling and
offsets in there, take a look at that too.
I hope someone smarter than me will chime in and correct any errors I may be
spreading -- but it should be OK for a FracRack!
