The respective min. and max. measured values are saved in the
sensor. The values are displayed in the menu item "Peak values Ad-
ditional".
This menu item displays the peak values of the electronics tempera-
ture as well as the dielectric constant.
In another window you can carry out a reset of the two peak values
separately.
The menu item "Echo curve" shows the signal strength of the echoes
over the measuring range in V. The signal strength enables an evalua-
tion of the quality of the measurement.
With the following functions you can zoom part sections of the echo
curve.
•
"X-Zoom": Zoom function for the meas. distance
•
"Y-Zoom": 1, 2, 5 and 10x signal magnification in "V"
