Solution
Selection of the solution from the solution list. We recommend always
selecting the solution. This ensures that the correct data (titer, concentra-
tion, etc.) is always used for the calculation. Solutions are defined under
System
▶ Solutions.
For buret units with integrated data chip, a check is made in the method
run to verify whether the correct solution has been attached and whether
the type of dosing drive matches. For buret units without integrated data
chip, the cylinder volume and the type of dosing drive are checked. The
validity of the titer is checked for the selected solution at the start of the
determination.

No check takes place.
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.
Input range –125 - 125 µA (Increment: 1)
Default value 50 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.
Input range –1250 - 1250 mV (Increment: 10)
Default value 400 mV
Electrode test
For polarizable electrodes, an electrode test can be carried out. A check is
made that the electrode is properly connected and that no short-circuit is
present. The electrode test is carried out when the determination is
started. This parameter is available only with I(pol) and U(pol) determina-
tions.
Selection on | off
Default value off
Stirrer
When this parameter is switched on, then the stirrer is switched on at the
start of the determination.
