VEGAPULS 67 • 4 … 20 mA/HART - four-wire
36532-EN-160224
In this menu item you can simulate measured values via the current
output. This allows the signal path to be tested, e.g. through down-
stream indicating instruments or the input card of the control system.
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 4 … 20 mA cur-
rent value and digital HART 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.
