If you have selected interface measurement under the menu item
"Setup - Application", the peak values of the interface measurement
are displayed in addition to the peak values of the level measurement.
In another window you can carry out a reset of the two peak values
separately.
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.
Information:
If one of the display values flashes, there is actually no valid value
available.
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"
