7.4 Sound level monitoring
The sound level monitoring is shown in a his-
togram. The distribution of recorded sound
levels within xed classes of valve position x
is revealed.
The leakage sensor records the sound level
every second and assigns the data into pre-
dened valve positions classes. The distribu-
tion showing how often the sound level oc-
curred within a valve position class is shown
in a bar graph.
Data are recorded in the background re-
gardless of the operating mode selected. Da-
ta logging does not need to be activated.
