6.2.1
Interval cleaning / weekly program
After expiration of the time interval, a cleaning
cycle is started at time t
0
, then the system
waits for another time interval to expire before
starting the next cleaning cycle. Fixed starting
times are defined for each day of the week in
the case of the weekly program.
6.2.2
Interval measurement
The electrode is outside the medium during
the dwell time and is only moved to the meas-
uring position for the duration of the measur-
ing time. Then the electrode is moved back to
the service position and cleaned.
