5.7 Checking the Settings
If two upper limits are set with one limit hig-
her than the other (g. 5-3), a pre-alarm is
triggered when the measured concentration
exceeds the rst limit (area B). If no corrrecti-
ve measures are taken and the concentration
exceeds the second limit (area C), a main
alarm is triggered.
Up to two alarms may be active per channel
at any one time.
