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
32 Technical specifications chapter, page 429.
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
32 Technical specifications chapter, page 429.
Input range –1,250 - 1,250 mV (Increment: 25)
Default value 400 mV
Electrode check
on | off (Default value: off)
For the following electrodes, an electrode check can be carried out:
￭ pH electrodes
￭ Metal electrodes
￭ Ion-selective electrodes
A check is made that the electrode is properly connected and that no
short-circuit is present. The electrode check is carried out when this com-
mand is started. Note that this electrode check has nothing to do with the
electrode test (command ELT).
Temp. measurement
Type of temperature measurement.
Selection continuous | automatic | off
Default value automatic
continuous
A temperature sensor must be connected. The temperature is mea-
sured continuously.
