You can find in the operating instructions manual "Indicating and ad-

justment module" also the description of the menu sections "Display"

and "Info".
In the main menu point "Setup", the individual submenu points should

be selected subsequently and provided with the correct parameters

to ensure the optimum adjustment of the measurement. The proce-

dure is described in the following.

Each medium has different reflection properties. With liquids, further

interfering factors are fluctuation product surface and foam genera-

tion. With bulk solids, these are dust generation, material cone and

additional echoes from the vessel wall.
To adapt the sensor to these different measuring conditions, the

selection "Liquid" or "Bulk solid" should be made in this menu item.

Through this selection, the sensor is adapted perfectly to the product

and measurement reliability, particularly in products with poor reflec-

tive properties, is considerably increased.
Enter the requested parameters via the appropriate keys, save your

settings with [OK] and jump to the next menu item with the [ESC] and

the [->] key.

Since a radar sensor is a distance measuring instrument, the distance

from the sensor to the product surface is measured. For indication of

the real level, an allocation of the measured distance to the percent-

age height must be carried out.
To perform the adjustment, enter the distance with full and empty ves-

sel. For instruments with standpipe antenna, these values are already

preset by default, see the following example:
