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 voltametric measurement.
The values that are actually adjustable may vary from the values specified
here, depending on the hardware. The binding values can be found in the
manual, in the "Technical specifications" chapter.
Input range –125.0 - 125.0 µA (Increment: 2.5)
Selection –1.0 µA | 1.0 µA
Default value 1.0 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.
ï¿ Generator electrode:
– Is the electrode connected?
– Is the generator system defective?
– Is the resistance of the sample solution very high?
The electrode check is carried out continuously during the execution of
this command.
Temp. measurement
Type of temperature measurement.
Selection continuous | automatic | off
Default value automatic
