Measured values of each channel will be displayed with 1% resolution (analog display).

the colors of the pens. Two ways of display can be selected:
Left-referenced (%) bargraph Center-zero bargraph
(center of the recording span is reference
and the deviation is displayed as a bargraph)
The squares underneath the bargraph show the occurrence of an alarm in the
