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.
Select the requested simulation variable and set the requested value.
Caution:
During simulation, the simulated value is output as 4 … 20 mA cur-
rent value and as digital HART signal. The status message within the
context of the asset management function is "
Maintenance
".
To deactivate the simulation, you have to push the
[ESC]
key and
confirm the message
with the
[OK]
key.
Information:
The sensor terminates the simulation automatically after 60 minutes.
The function "
Setup
" allows the echo curve to be saved at the time of
setup.
Information:
This is generally recommended, however, for use of the Asset
Management functions it is absolutely necessary. Saving should be
carried out with a very low level.
The function "
Echo curve memory
" allows up to ten individual echo
curves to be stored, for example to detect the measurement behav-
iour of the sensor in different operating conditions.
With the adjustment software PACTware and the PC, the stored echo
curves can be displayed with high resolution and used to recognize
signal changes over time. In addition, the echo curve saved during
setup can also be displayed in the echo curve window and compared
with the current echo curve.
