Setup
Procedure
• Set the potentiometer (1) to 0.
• Fill the vessel up to 100 mm below the
electrode.
• Turn the potentiometer (1) very slowly
clockwise until the status indication (2)
changes, i.e. lights in mode A, extinguishes
in mode B. Note the dial position of the
potentiometers (1).
• Continue filling the vessel until the measur-
ing probe is completely covered. With
measuring probes for adhesive products,
the sensitive tip must be covered com-
pletely (standard 100 mm above the elec-
trode). The status indication (2) changes
due to the additional filling.

Procedure
• Set the potentiometer (1) to 10.
• Fill the vessel up to the requested level or
pressure.
• Turn the potentiometer (1) very slowly
anticlockwise until the status indication (2)
changes, i.e. the status indication extin-
guishes.
• The signal conditioning instrument is now
ready for operation.
Please close with the transparent cover
