Start Up

Self-test

The device performs a self-test after switching on the power supply. It is ready for
operation and programming when the LCD displays the multi-display and the control
elements can be operated.
Note:
Frequent switching off and on of the devices causes aging of the electronics
(see Parameter 3. 1 ).

Multi-display

The multi-display shows on the LCD after a successful self-test with the output of the
level in the first line and the signal-to-noise ratio in the second line (factory setting):

Local Programming

When the mult-display shows on the LCD, you are ready to begin local programming
using the optical control elements. To access the parameter settings, touch the
element once. "Main Menu" is displayed in the first line of the LCD. Then program the unit
beginning with the Auto-Setup parameters.

• The nozzle height in the selected unit of length
• The vessel height in the selected unit of length)
• The LRV as a distance from the bottom of the vessel
• The URV as a distance from the bottom of the vessel
• The damping of the measured level in s.
• The application type
