Helpful article: What is ASR®?
Our patented Automatic Sensor Cleaning feature, or ASR®, keeps the electrodes' surfaces clean
and active, even in demanding and high-pollution applications. This makes our sensor low maintenance and improves accuracy when the correct cleaning frequency is selected.
To change your ASR frequency go to Main menu > In/Out > DIS > scroll down until you see "cleaning" > this provides you the ability to change your cleanings/week
Note: The cleaning frequency should match your application, and is water quality dependent. If you notice that the DIS signal is lower than the reference measurement but signal returns after a manual cleaning, this might indicate that ASR® frequency needs to be turned up. Available frequencies range from 1-7 cleanings per week.
