Pretitration
If the titration agent consumption is roughly known, you can set a pretitration volume on the
<Pretitration>
menu. In this process, a defined volume is dosed ( = pretitrated) following the initial
waiting time. After the addition of the pretitration volume, another defined span of time is observed as
the waiting time before the next titration step is added. The pretitration volume is automatically added
to the titration agent consumption. The pretitration volume can be set from 0.000 and 99.999 ml, the
possible range for setting the waiting time following pretitration is between 0 and 999 seconds.

Titration end
The end of a titration is reached, and the result will be calculated as soon as, or if, respectively:
The defined
End value
pH and mV value has been reached
The criteria (steep, flat,
slope value
) have been met for one turning point (
EQ1
) in the case of
a linear or dynamic titration.
The predefined value ml has been reached (
Maximum titration volume
)
or if titration was terminated manually by operating the <Stop> key.

It is also possible to switch off the criteria for the end value for pH and mV.
