Manual wash
Read 3.8 on Manual wash.
Select one out of “Disabled”, “Enabled”, “Di Imp2 high”, “E Imp2 high.”
When Manual wash is set to “Enabled”, you can run the wash cycle manually. For further
information read 3.8.
n
Imp.2 Wash sensors
Even after an error “Impedance2 too high” is detected, you can start Wash.
Go to “Manual wash” and select “Di Imp2 high” or “E Imp2 high.”
In this case, assign the sensor which has the error “Impedance2 too high” to Imp2. Wash.

Contact input Wash
If contact input is set to start Wash, you can start remote wash.
Read 4.2 Contact input.settings.

Continuous wash
Some electrodes tend to be easily contaminated during process measurement. To ensure
accurate reading, those electrodes might need continuous wash. However, Recovery time and
Interval time disturb the implementation of continuous wash.
The continuous wash starts once you set it to “Enabled.” First it runs in a measuring mode where
interval time is present. Then it moves to a washing mode and stays for the rest of the Wash time.

Continuous wash cycle
To restart the wash cycle after halting Wash, set “Continuous wash” to “Enabled” again. The
continuous wash requires special attention to be paid on sensor contamination created during
the cycle pause.
During “Continuous wash”, “Manual wash” or “Contact input Wash” is not available although it is
nominally settable.
