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 ▶ 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 ▶ 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:
￭ Polarizable electrodes
– Is the electrode connected?
– Is there a short circuit?
The electrode check is carried out when this command is started.
