Hello Todd,

many thanks for the reference schematics.

But that's not the SelfCAL module.

This should be capable of doing precise 10:1 ratio transfers, (I'm 
guessing), so recalibrating all ranges and reducing the T.C. You'll find 
this improvement (by a factor of nearly two) in the specifications, its 
key word is "Enhanced" specification

Maybe, when you find some time again, please have a deeper look into the 

Maybe, in the other service manuals, there might be a 'Theory of 
Operation' chapter?
