Correction factor for the powder output 

The OptiStar CG08(-C) gun control unit enables a zeroing out of the 
powder output. This allows for compensation to different powder hose 
lengths connecting to the pistol. 

The correction factor C0 can be selected such that no powder is output 
when the powder share is reduced to 0%. (see also "Initial start-up - 
Setting correction factor for powder output")
