0,250 … 0,600 m.
3. Adjustment
Under the menu point "
Adjustment“ you inform
the sensor with which meas. window it should
work.
You can carry out the adjustment without and
with medium. Generally you will carry out the
adjustment without medium as you can adjust
without filling cycle.

carry out directly adjustments with the small
MINICOM.
Adjustment steps
At the end of this chapter you see the com-
plete menu plan of the adjustment module
MINICOM. Set-up the sensor in the following
sequence. The numbers correspond to the
sequence of a set-up. The numbers are listed
with the appropriate menu points in the menu
plan.
1. Measurement in a standpipe (only carry out
when you measure in a standpipe).
2. Operating range
3. Adjustment
4. Conditioning
5. Meas. conditions
6. False echo storage (only necessary, when
errors appear during operation).
7. Indication of the useful and noise level
8. Outputs
1. Measurement in a standpipe
Adjustment only necessary when the sensor is
mounted on a standpipe (surge or bypass
pipe).
With a standpipe measurement a shifting of
the sound running time is caused which is
dependent on the inner diameter of the stand-
pipe. Measure the distance to the medium and
correct the measured value indication (which
can differ some percent from the measured
value) according to the measurement to con-
sider this shifting of the sound running time.
The sensor then corrects future shiftings of the
radar signal running time in the standpipe and
indicates the correct levels in the standpipe
(meas. pipe).
2. Operating range
Without special adjustment the operating
range corresponds to the measuring range.
The measuring range was already adjusted
with the min./max. adjustment. It is generally
useful to choose a slightly bigger operating
range (approx. 5␣ %) than the measuring
