lower sorting limits. The sorting and tolerance checking mode is
enabled and disabled with operating parameter P17.
Entering sorting limits
Sorting limits are entered in operating parameters P18 and P19
(see operating parameters).

(see section on X41) sort the display value into one of three
classes.
