Envelope curve with VU 331
After the basic setup, an evaluation of the measurement with the aid of the envelope
curve ("
envelope curve
"
(0E)
function group) is recommended.
Function "plot settings" (0E1)
Select which information will be displayed in the LCD:
•
envelope curve
•
env.curve+FAC (on FAC see BA 221F)
•
env.curve+cust.map (i.e. customer tank map is also displayed)
Function "recording curve" (0E2)
This function defines whether the envelope curve is read as a
•
single curve
or
•
cyclic.
!
Note!
If the cyclical envelope curve is active in the display, the measured value is refreshed
in a slower cycle time. It is therefore recommended to exit the envelope curve display
after optimising the measuring point.
!
Note!
An
orientation
of the Micropilot can help to optimise measurement in applications with
very weak level echos or strong interference echos by increasing the useful echo/
reducing the interference echo (see "Orientation of the Micropilot" on Page 86).
When using the Wave Guide antenna:
No
orientation is required!
