The reference rod is screwed into the sensor detector housing, thereby partially blocking the
sensor light. This simulates the absorbance in the optical chain.
The cross-sectional view of the measuring detector below illustrates the position of the
reference rod and its blocking effect.

Proceed as follows to obtain a value for the reference rod during commissioning:
1. Fill the flow assembly with water. Make sure that the measured value "zero" is displayed.
2. Insert the reference rod into the detector housing.
 Make a note of the measured value.
You can check the calibration any time later on by filling the flow assembly with water again
and re-inserting the reference rod. The measured value should be equal to the value noted
down.
8 Maintenance
Take all the necessary precautions in time to ensure the operational safety and reliability of
the entire measuring system.
NOTICE
Effects on process and process control!
‣
When carrying out any work on the system, bear in mind any potential impact this could
have on the process control system and the process itself.
‣
For your own safety, only use genuine accessories. With genuine parts, the function,
accuracy and reliability are also ensured after maintenance work.
