19.6. STOP CLEANING
Navigation
• Press and hold the
dr keys together to terminate a cleaning.
• During cleaning with the controller in normal measurement mode, the countdown timer will be displayed
on the second LCD line.
A complete rinsing phase (post‑rinse time) is always performed before terminating an advance cleaning. If the
request to stop the cleaning is issued during rinsing, the rinsing phase is carried out to completion.
Note: Calibration can’t be performed during cleaning; conversely, cleaning can’t be triggered during calibration.
A cleaning cycle can be stopped:
• At the end of a cleaning sequence, with the next cycle being triggered as per configured cleaning triggers.
•
At a stop command, with the current cycle being shortened to a maximum time, no higher than the sum of
a single rinse and recovery time. Next cycle will start as per configured cleaning triggers.
