auto
The current is adapted to the conductivity of the reagent and automat-
ically reduced near the endpoint. Default value, when Generator
electrode = with diaphragm.
Reagent monitoring
Selection of the reagent from the list of reagents. The selection depends
on the titration mode. Reagents are defined under System â–¶ Reagents.
Selection Selection of configured reagents | off
Default value off
off
The reagent monitoring is not active.
28.1.6 Sensor
The parameters for the sensor are edited under [Sensor].
Sensor
Selection of the sensor from the sensor list. The selection depends on the
measuring mode. Sensors are defined under System â–¶ Sensors. You can
also enter a sensor name which is not contained in the sensor list. When a
determination is started there is a check whether the sensor is contained
in the sensor list.
Selection Selection of configured sensors
I(pol)
The polarization current is the current that is applied to a polarizable elec-
trode during the voltametric measurement.
Selection 5 µA | 10 µA | 20 µA | 30 µA
Default value 10 µA
Electrode check
on | off (Default value: off)
For polarizable electrodes and the generator electrode, an electrode check
can be carried out. The following will be tested:
ï¿ Polarizable electrodes
– Is the electrode connected?
– Is there a short circuit?
The electrode check is carried out when this command is started.
