2. Select the requested simulation variable with
[->]
and confirm
with
[OK]
.
3. With
[OK]
you start the simulation, first of all the actual measured
value is displayed in %
4. Start the editing mode with
[OK]
5. Set the requested numerical value with

and
[->]
6. Push
[OK]
Note:
During simulation, the simulated value is outputted as Profibus PA
signal.
How to interrupt the simulation:
→
Push
[ESC]
Information:
The simulation is automatically terminated 10 minutes after the last
pressing of a key.
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 entire measuring range.
A comparison of echo curve and false signal suppression allows a
more detailed statement about measurement reliability.
The selected curve is continuously updated. A submenu with zoom
functions is opened with the
[OK]
key:
•
"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
without magnification
The function "
Echo curve memory
" makes it possible to save the
echo curve at the time of setup. This is generally recommended, and
it is absolutely necessary if you want to use the Asset Management
functions. If possible, the curve should be saved with a low level in the
vessel.
With the adjustment software PACTware and a PC, a high resolution
echo curve can be displayed and used to recognize signal changes
during operation. In addition, the echo curve of setup can be dis-
