• 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
5)
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 as defined by the Tank/silo height parameter
(→  142). By default, Tank/silo height = Empty calibration .
Take into account that in case of conical outlets, for example, a measurement is only
possible up to the point at which the radar hits the bottom of the tank or silo. If the
Tank empty option is used, Empty calibration (→  128) and Tank/silo height may
not reach below this point as otherwise the empty signal is suppressed.
• 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.
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.
