VEGAFLEX 81 • HART - integrated accumulator

This menu item displays the peak values of the electronics tempera-
ture as well as the dielectric constant.
In another window you can carry out a reset of the two peak values
separately.
The menu item "Echo curve" shows the signal strength of the echoes
over the measuring range in V. The signal strength enables an evalua-
tion of the quality of the measurement.
With the following functions you can zoom part sections of the echo
curve.
•
"X-Zoom": Zoom function for the meas. distance
•
"Y-Zoom": 1, 2, 5 and 10x signal magnification in "V"
•
"Unzoom": Reset the presentation to the nominal measuring range
with single magnification
In this menu item you can simulate measured values via the current
output. This allows the signal path to be tested, e.g. via downstream
indicating instruments or the input card of the control system.
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.
