Fig. 6.8.2 Display range settings
(2) Reading echo curve data
To read echo curve data, click [Echo Curve] --> "Read" button. After reading starts, wait
momentarily until the processing progress on the status bar stops. If the echo curve data is read
normally, The echo curve similar to that in the following window (example) and the noise table
that was simultaneously read will be displayed in the graph. At this time, if you set the echo
peaks display in graph option in the echo viewer operation area to ON ( ), the echo list
that was simultaneously read will be superimposed on the graph. If you want to continuously
read echo curve data, once echo curve data begins to be read in a state of setting Auto Read in
the echo viewer operation area to ON ( ), the echo curve data will be continuously
read during the period that Auto Read is ON. If you want to stop Auto Read, set it to OFF
( ). After final reading is complete, Auto Read will stop. If you want to display range of
R in the graph, set the R display in graph option in the echo viewer operation area to ON ( ),
Also, If you want to display range of C in the graph, set the C display in Graph Option in the
echo viewer operation area to ON ( ). If you want to display “Threshold Value” in the graph,
set the “Threshold Level” from the graph option in the echo viewer operation area by check
( ).
