The "Echo curve" shows the signal strength of the echoes over the
measuring range in dB. The signal strength enables an evaluation of
the quality of the measurement.
The "False signal suppression" displays the saved false echoes (see
menu "Additional settings") of the empty vessel with signal strength in
"dB" over the measuring range.
A comparison of echo curve and false signal suppression allows a
more accurate conclusion on measurement reliability. The selected
curve is continuously updated. With the [OK] key, a submenu with
zoom functions is opened:
•
"X-Zoom": Zoom function for the meas. distance
•
"Y-Zoom": 1, 2, 5 and 10x signal magnification in "dB"
•
"Unzoom": Reset the presentation to the nominal measuring range
with single magnification
The "Echo curve" shows the signal strength of the echoes over the
