Range of mapping (052) function
• The range of mapping is displayed, confirm the proposed value or enter your own value
• The sensor membrane is always the reference point
• The value can be edited by the user
• For manual suppression (mapping), the default value is 0 m
The mapping range must end 0.5 m (1.6 ft) before the echo of the actual level. If the
tank is empty enter E – 0.5 m instead of E.
Start mapping (053) function
Selection
• Off: no mapping
• On: mapping starts
If a mapping already exists, it will be overwritten up to the distance specified. The
existing mapping remains unchanged beyond this distance.
Dist./meas.value function (008)
Information displayed after mapping
Distance measured from the sensor membrane to the product surface
Check whether the values displayed match the actual distance or actual level.
The following situations can occur:
• Distance and level correct: Basic setup completed
• Distance and level incorrect: perform another mapping in the Check distance (051)
function
• Distance is correct but the level is incorrect: check the value in the Empty calibration
(005) function
Return to group selection
After the mapping has been recorded the basic setup is finished and the device
automatically returns to the group selection.
9.5 Displaying the envelope curve
Check the measurement: after the basic setup, select the Envelope curve (0E) function
group.
After the basic setup, it is advisable to evaluate the measurement using the envelope
curve:
• Recognition of interference echoes
• Recognize whether interference echoes are completely suppressed by interference
echo suppression (mapping)
9.5.1 Plot settings (0E1) function
Selection
• Envelope curve
• Envelope curve and FAC
• Envelope curve and mapping
For information on the FAC and mapping, see the documentation BA "Description of
Device Functions".
9.5.2 Recording curve (0E2) function
Selection
• Single curve
• Cyclic
