7.1. Special methods

The PF-12 allows you to define up to 20 special methods. The methods can
be defined as linear (factor) or non-linear methods (up to the 4th degree). For
defined methods, the same options as in the main program, such as sample lo-
cation, dilution, memory, etc. are available.
Now follows the menu for entering the method characteristics. To enter text,
filter query, factor, measurement direction, measurement range, unit and dimen-
sion addition, you can enter letters and numbers via the key pad.
At the query <factor linear?>, you have two options. You can press
a linear factor (β = E x F). In this case, the decimal place of the factor also indi-
cates the displayed decimal places.
Alternatively, you can press
F4 x E4 + F3 x E3 + F2 x E2 + F1 x E + F0). Pressing button
a polynomial factor results in a change of the algebraic sign. Once you have
entered the polynomial factors, you can enter the number of decimal places
in the display and the measurement direction (+ = increasing, - decreasing,
+- both directions).
You can delete and re-enter an erroneous entry at any time by pressing
