Setting Krypton® Multi ASR® Cleaning Frequency – Kuntze Instruments GmbH

Overview

This article explains how to set the ASR® cleaning frequency for Krypton® Multi and how to select a suitable interval for real process conditions.

Helpful article: What is ASR®?

Purpose of the ASR® Setting

ASR® (Automatic Sensor Cleaning) helps keep electrode surfaces active by limiting fouling buildup. Correct frequency selection supports stable measurement values and reduces manual maintenance.

Menu Path

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

Main menu > In/Out > Multi > Cleaning

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

Recommended Setting Strategy

Start with a low cleaning frequency and increase only if fouling is observed.
Do not configure frequent cleaning by default if process conditions are stable.
ASR® is intended to keep the sensor clean during operation, not to recover a heavily fouled sensor.
If the sensor is already dirty, perform manual cleaning first, then use ASR® to maintain the clean condition.

Available Frequency Range

Configurable up to 1 cleaning per day (7 cleanings per week).
Use the lowest effective setting for your application.

Operational Notes

After each setting change, observe the trend over several operating cycles.
If drift persists, verify sample quality, flow conditions, and sensor condition before increasing frequency further.
Re-check settings after process changes or seasonal water-quality changes.
