Adjustment steps
On the following pages you will find the com-
plete menu schematic of the adjustment mod-
ule MINICOM.
Set up the sensor in the numbered se-
quence:
1. Measuring tube adjustments (only for
measurement in a standpipe)
2. Operating range
3. Adjustment
4. Conditioning
5. Meas. conditions
6. False echo storage (only required when
errors occur during operation).
7. Indication of the useful and noise level
8. Outputs
Short explanations to the setup steps 1 … 8
follow.
1. Measurement in a standpipe
Adjustment is only necessary if the sensor is
mounted in a standpipe (surge or bypass
tube). When measuring in a standpipe, do a
sounding of the distance and correct the
measured value display (which can differ
several percent from the sounded value)
according to the sounding. From then on, the
sensor corrects running time shift of the ra-
dar signal and displays the correct value of
the level in the standpipe (measuring tube).

5.3 Adjustment with adjustment
module MINICOM
You can set up and operate the sensor with
the small, detachable adjustment module
MINICOM just as well as with the PC. The
adjustment module is simply plugged into the
sensor or into the external indicating instru-
ment (optional).
The adjustment module, like the adjustment
program VVO on the PC, provides adjust-
ment options for all sensor versions. There
are some differences with MINICOM, how-
ever. For one thing, it is not possible to enter
your own linearisation curve.
You carry out all adjustment steps with the 6
keys of the adjustment module. A small dis-
play shows you, apart from the measured
value, a short message on the menu item or
the value entered in a menu item.
The volume of information of the small display
cannot be compared with that of the adjust-
ment program VVO, but you will quickly find
your way and carry out your adjustments
quickly and efficiently with the small
MINICOM.
