•
"Y-Zoom": 1, 2, 5 and 10x signal magnification in "dB"
•
"Unzoom": Reset the presentation to the nominal measuring range
without magnification
With the function "Echo curve memory" the echo curve can be saved
at the time of setup. This is generally recommended; for using the As-
set Management functions it is absolutely necessary. If possible, the
curve should be saved with a low level in the vessel.
With the adjustment software PACTware and the PC, the high resolu-
tion echo curve can be displayed and used to recognize signal
changes over the operating time. In addition, the echo curve of the
setup can be also displayed in the echo curve window and compared
with the actual echo curve.
