User Manual

Enter the requested parameters via the a ppropriate keys, save your
settings with [OK] and jump to the next menu item with the [ESC] and
the [->] key.
As a radar sensor is a distance measuring instrument, the distance
from the sensor to the product surface is measured. To have the real
product level displayed, an allocation of the measured distance to the
percentage height must be made. To carry out this adjustment, the
distance is entered with full and empty vessel. If these values are not
known, an adjustment with the distance values, e.g. 10 % and 90 % is
also possible. Starting point for these distance specifications is always
the seal surface of the thread or flange. By means of these settings,
the real level is calculated.
The real product level during this adjustment is not important, because
the min./max. adjustment is always carried out without changing the
product level. These settings can be made ahead of time without the
instrument having to be installed.
Proceed as follows:
1 Select the menu item "Setup" with [->] and confirm with [OK]. Now
select with [->] the menu item "Min. adjustment" and confirm with
[OK].
2 Edit the percentage value with [OK] and set the cursor to the
requested position with [->].
3 Set the requested percentage value with [+] and save with [OK].
The cursor jumps now to the distance value.
4 Enter the suitable distance value in m for the empty vessel (e.g.
distance from the sensor to the vessel bottom) corresponding to
the percentage value.
5 Save settings with [OK] and move with [ESC] and [->] to the max.
adjustment.
