900 Touch Control
29.1.6 Sensor
The parameters for the sensor are edited under [Sensor].
Measuring input
Selection of the measuring input the sensor is connected to. The selection
is not dependent on whether the control device has one or two measur-
ing interfaces.
Selection 1 | 2
Default value 1
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. This parameter is available
only with I(pol) determinations.
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
"Technical specifications" chapter for the control device used.
Input range –125.0 - 125.0 µA (Increment: 2.5)
Default value 5.0 µA
Selection –1.0 µA | 1.0 µA
U(pol)
The polarization voltage is the voltage applied to the polarizable electrode
during an amperometric measurement. This parameter is available only
with U(pol) determinations.
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
"Technical specifications" chapter for the control device used.
Input range –1,250 - 1,250 mV (Increment: 25)
Default value 400 mV
