The selection tree:
The display selections are structured like a tree as shown in Figure 2.61. Using the soft keys (A, B, C, D) it
is possible to select the next display upwards. In some cases the selection is made from a menu using a
numerical key. In Figure 2.61 the Soft Key selection is indicated by letters A-D, menu selection by
numbers 1-9. The display itself provides guidance to find the right path step-by-step, which minimizes the
need to consult the manual.
The RESET key is used to climb down the tree, for each RESET the next display downwards is selected.
Data entry:

horizontal scale expresses the numbers of the photocells 0-256. The three leftmost pulses represent
additional dark reference cells.
