Regression accuracy: Characteristic value to evaluate the description of the measured values by the
polynomial. Larger values are better. A value of 1 means perfect agreement. The regression accuracy is
calculated automatically.

setting is Auto. Alternatively it can be set manually. Allows to manually move the average slope (display
optimization).
The following settings can be made in the menu under Apply.
