Full calibration Enter the distance (LF) between
the minimum (0%) and the
maximum level (0%). The
minimum is the bottom of the
probe and the maximum is the
"full" level.
Level Displays the measured level
(LL) of the material before
linearization. The unit is defined
in the Level unit setting.
Distance Displays the distance (LD)
between the lower edge of the
flange or threaded connection
(LR) and the level (LL).
Signal quality Displays the signal quality of the
evaluated echo.
• Strong: Exceeds the threshold
by 10 mV or more.
• Medium: Exceeds the
threshold by 5 mV or more.
• Weak: Exceeds the threshold
by less than 5 mV.
• No signal: The device cannot
find a usable echo. The system
displays an error message for
output echo lost.
NOTE: The signal quality refers
to the level/interface echo or
the end-of-probe echo. The
quality of the end-of-probe echo
is displayed in brackets.
Confirm Specify whether the measured
distance distance matches the actual
distance.
• Manual map: The range of
mapping is defined manually
in the Mapping
parameter.
• Distance OK: The measured
distance matches the actual
distance.
• Distance unknown: The actual
distance is unknown.
• Distance too small: The
measured distance is less than
the actual distance.
• Distance too big: The
measured distance is more
than the actual distance.
• Tank empty: The tank is
completely empty.
• Delete map: Delete the present
mapping curve.
