3. The following relationship exists between the number of display dots on
the screen, the content of the numeral table reference, and the 100% val-
ue.

(100% data value)
If the results for a bar graph display is over 100%, a 1-dot blank will be
displayed past the size set with the Support Tool and an 8-dot bar will be
display beyond the blank to indicate a value over 100% (see below).
