delay. In this phase, additions were made by titration at linear increments. But once the desired pH is reached, it
is immediately switched to the second stage, the actual pH-stat level. This means that the drift control is now
omitted and a fixed waiting period of "zero" seconds occurs between the titration stage and the measurement
value acquisition. This is also necessary; otherwise you could not maintain the pH value over a set period in
many cases.
During the titration, the pH/time or the ml/time curve and the pH value/ml can be displayed analog.
