QTR-Quadtone RIP

This is my first time working with QTR & The User Guide, the following seems to be a contradiction.

The guide states:

To print the first Ink Separation Test Page, place a piece of the paper for

which the Curve will be designed in the printer, make sure the calibration

slider is all the way to the left (100), click the Print button and you’re

off.

In my QTRgui, all the way to the left results in a value of 0. So which do I use?
