15.13.4 Activating a user-defined damping of the values of the
acoustic transmission factor
The damping makes it possible to damp the fluctuations of the measured values of the acoustic trans -
mission factor:
• on the display,
• on the totalizers,
• on the outputs. The damping set for an analog output comes in addition to the damping of the acoustic
transmission factor.
By default, the measured values of the acoustic transmission factor are damped with the level None .
To damp the fluctuations of the measured values, you can:
→
either choose 1 of the 3 predefined damping levels:
Low
,
Medium
or
High
. See chapter 15.13.3 .
→
Or you can set your own damping parameters with the Special damping.
With the Special damping, you can set 2 parameters:
• a user-defined
Response time
in seconds,
• the Jump threshold , i.e. a user-defined percentage. If 2 consecutive measured values vary for ± the per -
centage, no damping is applied to the second measured value.
To set your own damping parameters of the DF values, do the following:
→
Go to the
