Additional information Meaning of the options
• Manual map
To be selected if the range of mapping is to be defined manually in the Mapping end
point parameter (→ 171). In this case it is not necessary to confirm the distance.
• Distance ok
To be selected if the measured distance matches the actual distance. The device
performs a mapping.
• Distance unknown
To be selected if the actual distance is unknown. A mapping can not be performed in this
case.
• Distance too small
To be selected if the measured distance is smaller than the actual distance. The device
searches for the next echo and returns to the Confirm distance parameter. The distance
is recalculated and displayed. The comparison must be repeated until the displayed
distance matches the actual distance. After this, the recording of the map can be started
by selecting Distance ok.
• Distance too big
10)
To be selected if the measured distance exceeds the actual distance. The device adjusts
the signal evaluation and returns to the Confirm distance parameter. The distance is
recalculated and displayed. The comparison must be repeated until the displayed
distance matches the actual distance. After this, the recording of the map can be started
by selecting Distance ok.
• Tank empty
To be selected if the tank is completely empty. The device records a mapping covering
the complete measuring range.
• Factory map
To be selected if the present mapping curve (if one exists) is to be deleted. The device
returns to the Confirm distance parameter and a new mapping can be recorded.
When operating via the display module, the measured distance is displayed together
with this parameter for reference purposes.
For interface measurements the distance always refers to the toatal level (not the
interface level).
If the teaching procedure with the Distance too small option or the Distance too big
option is quit before the distance has been confirmed, a map is not recorded and the
teaching procedure is reset after 60 s.
For FMP54 with gas phase compensation (product structure: feature 540 "Application
Package", option EF or EG) a map must not be recorded.
Present mapping
Navigation Setup → Present mapping
Description Indicates up to which distance a mapping has already been recorded.
