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 measuring range.
A comparison of echo curve and false signal suppression allows a
more detailed statement of the 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
