The individual histogram displays consist of a dual segment
analysis (DSA), which show the current value and the
minimum value. This DSA is shown in fig. 15. The narrow
segment stands for the current value and the wide segment
shows the minimum value, which is of particular significance
when looking for burst pipes.

With the first push of the mute button

the current
measurement is stored and simultaneously displayed. In this
way, nine values can be stored, one after the other. When
more than nine values are measured, the first value will be
deleted and all other values will be shifted one position to the
left. The last nine values are thus always available.
