The values put in ascending order are automatically adjusted so they are in the
neighboring positions of the array, irrespective of the position in the linearization
table.

Aged ASCs can suffer from wearing of the position-indicating potentiometer. The
potentiometer gaps are identified during the calibration and the number of the gaps is
displayed on the HMI after the calibration. Actual gap locations GAP_LO_VAL_x
and GAP_HI_VAL_x (x = 1...5, which corresponds to the gap identification number)
