Volume windows are defined sub-regions (windows) on the volume axis for
which different parameters for the potentiometric evaluation can be
defined. Only those endpoints which lie within these windows and addi-
tionally meet the parameters defined for each window will be recognized.
Only one endpoint will be recognized per window.
