• Confirm the adjustments with " OK OK OK OK OK“ and
after a message is displayed, you are
again in the menu window "
Adjustment“.
Setup
• Choose " no (adjustment without medium) no (adjustment without medium) no (adjustment without medium) no (adjustment without medium) no (adjustment without medium)“.
In the menu window "Min/Max-Adjustment“
you choose e.g. the level distance corre-
sponding to 100 % and 0 %. Of course, you
can also enter the distance values e.g. at
20 % and 75 % filling.
If the two points are too close together, e.g. at
45 % and 49 %, a considerable meas. error
can result, as the sensor generates by
means of the two adjustment points a linear
correlation between filling volume (%) and
meas. distance.
• Choose if you want to carry out the adjust-
ment in meters (m) or in feet (ft).
• Enter a distance for the upper and lower
level and the extent of filling in % corre-
sponding to each distance.
In the example, the 0 % filling is at a product
distance of 5.850 m and the 100 % filling at a
product distance of 1.270 m.
Offset
See also A3-1 in chapter "6 Function dia-
gram“ under "Level Offset“.
Note:
The sensor is delivered with the sensor
measuring range set to the same value as
the operating range. After the sensor has
been adjusted, the operating range corre-
sponds to the adjustment range. The sensor
can only detect levels within the defined oper-
ating range. For level detection outside the
operating range (if you want to detect e.g.
108 % and -10 %), the operating range must
be corrected respectively in the menu "
Sen-
sor optimisation/Meas. environment“ (see the
following chapter "Sensor optimisation“,
"Meas. environment/Operating range“).
• Click in the menu window " Adjustment“ to
" Quit Quit Quit Quit Quit“.
You are again in the menu window " Instru-
ment data parameter adjustment“.
