Functional test
A functional test can only be carried out after the transmitter has been
dismantled.
During the functional test, unintended process operations can be activated in the
downstream control unit. Risk of property or personal damage.
1. Remove the connection cable
2. Connect the ohmmeter to two wires
3. Move the float from the min. to the max. position
4. The indicated resistance value changes depending on the connected wire colours (Tab. 1).
Note
Black - Brown (R1)
The resistance value increases
proportionally to the height of the rising
magnet system (float).
Magnet system (float) at the top - indication
of the total resistance (Ri)
The total resistance Ri of the measuring chain is dependant on the transducer length and type.

Functional testing may trigger unintended reactions in subsequent control
circuits. Risk of property damage or personnel injuries.
