Operation
Function test
1. To check the functions of the conductivity transmitter, set code switch 10 to ON. This simulates a
value that exceeds the measuring range limit and provides a current output of 20 mA.
2. After finishing the function test, set the code switch back to OFF.
Code switch 10 Function test
OFF Normal operation
ON Simulation: measuring range limit exceeded
The two LEDs in the middle of the electronic circuit board indicate the status of
the conductivity transmitter.
