Identify the expected measuring value is measurable with the installed optical path
length.
3.
Measure the optical path length of the sensor. Make sure that the correct length is set
in the controller settings. Refer to the controller documentation for more information.
4.
Clean the measuring windows. Refer to
on page 15.
