Setting Krypton® DIS ASR® Cleaning Frequency

Overview

This article explains how to set the ASR® cleaning frequency for Krypton® DIS sensors and how to choose a suitable interval for process conditions.

Purpose of ASR® Frequency Setting

ASR® (Automatic Sensor Cleaning) keeps electrode surfaces active by reducing fouling buildup. Correct frequency selection helps maintain signal stability, reduce manual cleaning effort, and improve long-term measurement consistency.

Menu Path

To adjust the ASR® cleaning frequency on Krypton® DIS:

Main menu > In/Out > DIS > scroll to Cleaning

In this menu, set the number of cleanings per week.

---

Available Frequency Range

• Minimum: low weekly frequency (application-dependent).
• Maximum: up to 1 cleaning per day (7 cleanings per week).

---

Operational Notes

• Select frequency based on actual fouling tendency and process contamination level.
• Start with a moderate setting, then optimize using trend stability and maintenance feedback.
• If drift or response delay persists, verify flow/sample conditions and sensor status before increasing frequency further.
• After changing settings, observe readings over several operating cycles to confirm stability.
