• Enter here the checked product distance

Hence you cause the sensor to mark all ech-
oes in front of the level echo as false echoes.
This avoids that the sensor detects errone-
ously a false echo as level echo.
• Click to "Show echo curve“.
The echo curve and the false echo marking
are shown.
Set-up
You see that due to the strut, the false echo is
approx. 20 dB lower than the useful echo and
can therefore no more influence the measure-
ment.
• Quit the menu window "Echo curve“ with
"Quit“.
With the menu point " False echo storage“ in
the menu window " Sensor optimisation“ you
cause the sensor electronics to mark false
echoes and to save in a database. The false
echoes are then treated different than the
useful echo.
• Click in the menu window " Sensor optimisa-
tion“ to the menu point "False echo stor-
age“.
• Click in the menu window " False echo stor-
age“ to "Learn false echoes“. The small
window "
Learn false echoes“ opens.
