Section 7. Service Functions
7.10.1 Graph Area When the Tank Scan window opens, WinSetup reads tank data from the
gauge. The process is indicated by a progress bar in the lower right corner of
the Tank Scan window.
Once the reading process is finished, a tank scan graph is displayed that
shows a peak referring to the product surface. The Tank Scan graph may
also contain other peaks. In addition to the surface echo, there might be
echoes from agitators or other obstacles in the tank. The Tank Scan function
includes tools that allows you to configure the level gauge to distinguish
between the surface peak and peaks from disturbing objects. See the
following chapters for details.
The Tank Scan graph can be refreshed at any time with the Reread From
Gauge button. The new echo curve will appear as a black line and the
previous curve as a grey line. The graph may show up to two old echo curves.
An old echo peak will be marked by a small cross symbol. This can be used to
compare the existing tank signal with previous signals.
