• Distance too big
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).
For FMP55 with rope probes and Operating mode (→  126) = Interface with
capacitance the mapping must be recorded with the tank being empty, and the Tank
empty option must be selected. Otherwise the device can not register the correct
empty capacitance.
For FMP55 with coax probes a mapping must be recorded at least in the upper part of
the probe, as tightening the flange has an influence on the envelope curve. However,
even with coax probes it is recommended to record the mapping with the tank being
completely empty (and selecting the Tank empty option).
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.
 Setup → Present mapping
