Alarm delay
In some applications (for instance during pump down in a „chamber test
system“) it might be necessary to block an alarm for some time after pres-
sing START.
This delay time of the alarm can be changed.
After pressing START the loudspeaker is activated as soon as the leak
rate drops below trigger level 1 or after the entered alarm delay time has
elapsed. This setting is only active for the audio alarm types SETPOINT
and TRIGGER ALARM (See Chapter
6.4.7
).
