Linearization Problems

2015-03-04 by homershannon@...

I'm relatively new to QTR but have my basic qdif file worked up and printing. I want to use the linearization panel to correct the curve a bit.


The linearization panel does not look like the panel described in Tom Moore's instructions. The instructions show a 21 field table. The current version (2.7.0.0) of QTR has 10 x 6 table. I assume I need to use the first 21 fields and entered my densities from my step scale scan. The last three values were all 94 and I know this causes issues. Nevertheless, I attempted to save the file and got the message "Invalid linearization curve -- not constantly increasing". I changed the 94 values to 93, 93.5 and 94 and got the same message. I then tried entering the LAB values and I still get the message.


How do I enter the 21 values correctly into this field so that I can linearize the curve?
