Figure 5-24 Measuring range switch, type A
When the upper switch point (OU) is exceeded, the next greater available measuring range
is selected. If the lower switch point (UU) of the next smaller available measuring range has
fallen short, this is selected. The UU lies at 80 % (HystA) of the measuring range. The OU
lies at 90 % (HystE) of the measuring range.
Type B:
The full-scale value must be greater than or equal to the full-scale value following it. Since
the measuring spans must simultaneously become greater, the measuring range start-of-
scale values of the following measuring ranges become continuously smaller.
