Envelope curve with VU331
After the basic setup, an evaluation of the measurement with the aid of the envelope curve
("
display
"
(09)
function group) is recommended).
Function "plot settings" (09A)
Here you can select which information is shown on the display:
•
envelope curve
• env. curve+FAC (for FAC see BA00217F/00/EN)
• env. curve+cust.map (i.e. the tank map is also displayed)
L00-FMRxxxxx-07-00-00-en-004
Function "recording curve" (09B)
This function determines whether the envelope curve is read as:
•
single curve
or
• cyclic
!
Note!
• If the envelope curve mode is active on the display, the measured values are updated in a slower
cycle time. Thus, it is advisable to leave the envelope curve mode after the measuring point has
been optimised.
• If the level of echo is very weak or there is a heavy interference echo, an
orientation
of the
Micropilot can contribute to an optimisation of the measurement (increase of the level echo/
reduction of the interference echo) ("Orientation of the Micropilot",
74).
