How to start the simulation:
1. Push
[OK]
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
