2.1.1 Table fields
A statement on the quality of the correlation graph is made. The
assessment ranges from 0 – 100%. The settings for the display of a
possible or probable leak are made under Administration in Settings.
Maximum describes the maximum of the correlation curve and provides
additional information on the Quality field. The assessment ranges from
between 0 and 100, where 0=no signal matching and 100=full signal
matching. In general, the higher the value, the better the correlation.
Reference number of the first logger that was correlated.
Distance L1 specifies the distance between Logger 1 and the noise source.
This is the total pipe length between Logger 1 and Logger 2.
Distance L2 specifies the distance between Logger 2 and the noise source.
Reference number of the second logger that was correlated.
The calculated or entered sound velocity is displayed here.
Located in the Pipe Setup field are red, orange or green indicators.
Red indicators indicate that no pipe settings have been entered yet and the
used data were taken over from the default values.
Orange images appear if manual settings were made and not all details are
known (pipe length, diameter and material are known). With manual
settings, the course of the pipe cannot be changed, unlike with the Pipe
Wizard.
Green indicators mean that all details are known for the settings and were
taken over in full from the Pipe Wizard.
To enter the pipe settings, use the mouse to click the small arrow in the
field that you would like to change. In the menu that appears, select Manual
Pipe Data Entry if you would like to enter the data "manually" or Start Pipe
Wizard if the data are to be determined automatically. To delete existing
pipe data, select the Delete Pipe Information item.
