What does the error "REF TOO LOW" on Ultraturb Sensor mean?
Summary
Ultraturb REF TOO LOW error
Answer
The "REF TOO LOW" error on the Ultraturb Sensor means that the reference light used for analysis is not being seen by the photo detector. This is normally from the analysis cell being empty or from it being very dirty. Ensure that the sample/analysis chamber is both clean and filled with water.
