VEGAFLEX 81 • 4 … 20 mA/HART two-wire
42279-EN-130612
Select the requested simulation size and adjust the requested value.
Caution:
During simulation, the simulated value is outputted as 4 … 20 mA cur-
rent value and digital HART signal.
Push the [ESC] key to deactivate the simulation.
Information:
The simulation is terminated automatically 60 minutes after the last
key has been pushed.
With the menu item "Setup" the echo curve it is possible to save at
the time of setup. This is generally recommended; for using the Asset
Management functions it is necessary. If possible, the curve should
be saved with a low level in the vessel.
With this, you can detect signal changes over the operating time. With
the adjustment software PACTware and the PC, the high-resolution
echo curve can be displayed and used to compare the echo curve of
the setup with the actual echo curve.
The function "Echo curve memory" enables storing echo curves of
the measurement.
Under the sub-menu item "Echo curve memory" you can store the
current echo curve.
Parameter settings for recording the echo curve and the settings of
the echo curve itself can be carried out in the adjustment software
PACTware.
With the adjustment software PACTware and the PC the high-reso-
lution echo curve can be displayed and used later on to assess the
quality of the measurement.
Entering a 4-digit PIN protects the sensor data against unauthorized
