Electrode test
In the case of 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 as soon as the
determination is started.

7.1.5 Stop conditions
Menu ▶ Parameters ▶ Stop conditions
The conditions for stopping a titration are defined under Stop condi-
tions, if this does not occur automatically. This could be the case when
the endpoint set is not reached or if the stop criterion (see "Stop crite-
rion", page 78) is not fulfilled.
Stop time
The titration is canceled when the specified time has elapsed since the
start of the titration.
Input range 1 ... 999999 s

7.1.6 Calculation
7.1.6.1 General
Menu ▶ Parameters ▶ Calculation
A maximum of five calculations can be defined in one method. A series of
variables (raw data from the determination, previously calculated results) is
available for the calculations. Definition can be made for each calculation
as to whether the result is to be saved as a common variable.
