Dave, Good Idea,  I will change all the cables.
Thanks,

Chris, Also good Idea,  Perhaps, I could take a  battery, and reduce it with 
resisters, to a known voltage, I don't have a variable power supply. 
Confirm these voltages with a meter, something like 100mv 200,300,500 etc 
all the way up to +10v, then -10v.

It only seem to clip on large negative numbers, so I could rig up a +9 and 
a -9 volts, to see if it measure these incremental inputs.

Thanks, All
Ted
