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 sensors 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. Available frequencies are up to 1 time per day or 7 times a week.
