7 Configuration
Device dialog – counter/integrator 1 ... – limit value monitoring function (alarm 1, alarm 2)
Limit value monitoring with one or two limit values (alarm 1, alarm 2) can be activated for each counter/
integrator. In out-of-limit cases, an alarm signal is activated. Depending on the configuration, an entry is
made in the event list or additionally in the alarm list. In the latter case, the alarm/event text is displayed
in the status bar (until another alarm occurs); the collective alarm is enabled, and the plotter trace may
be displayed in a different color.
