3.8.5 Volume
Main menu > Trigger & Alarms > Volume
The minimum loudness and the actual volume of the loudspeaker can be adjusted.
The minimum loudness is the minimum speaker volume that cannot be exceeded
to even lower values. Thus it is avoided that the actual volume is accidentally
adjusted to a value that is below the noise level of the environment.
The actual volume can be adjusted between 15 (maximum) and the value defined
as minimum loudness.
3.8.6 Alarm Delay
Main menu > Trigger & Alarms > 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 pressing 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 3.8.7).
