Enter how often measurements are to be taken. ATTENTION with filtration probe and 5min
operation: increased pump speed in the filtration probe, annual filtration probe maintenance is
necessary instead of every 2 years.
WET/DRY, decides if the cuvette is empty (DRY) or filled (WET) between measurements at
measurement intervals that are equal or greater than 10 minutes. Adapt individually for
smoothest measurement values.
YES/NO, decides if the instrument is measuring continuously or measurements are triggered
by field-bus. The "Fieldbus" option must be activated in the Test/Maintenance menu. The
instrument will switch to a 5 min interval when activated.
Number of measurements that are taken after one activation by bus.
Number of discharged values that precedes the measurements.
Number of measurements that are averaged. (effects bus triggered measurements only)
Number of hours between the cleanings.
Start time for the cleaning (in case of more than one cleaning per day: start time for the first
cleaning)
Number of measured values that are discarded after a cleaning operation.
Value output during a cleaning operation and the following discarded values. HOLD = last
measured value, SET TRANSFER = value to be entered
Probe tube heating switches on at the start of the selected month. With filtration probe.
Probe tube heating switches off at the end of the selected month. With filtration probe.
On/Off: On determines the warning output if the reagent levels are low.
Determines the level below which the reagent must drop to trigger the warning.
Warning is released, when a filter probe is installed and the status of filtration modules falls
below the defined level.
Status of filtration modules at filter probe at which an error is generated. When switched to
OFF, a deactivated sample detection will be switched to "warning".
Determines instruments reaction when amount of available sample is to low. When
instrument is in filter probe mode, deactivating the sample detection will switch a deactivated
"STATUS MODUL.ERR" to 14 %
Determines instrument reaction when drain is blocked
Determines if measurement reference channel is used for measurement or not.
Use for samples that produce gas when acid is added. If active, sample is removed from
cuvette after reagent has been added, then refilled again to remove bubbles. If active, the
measurement interval of 5 minutes is not available. For not degassing samples the
measurement values are smother with bubble rejection deactivated.
