Drift-controlled acceptance of the measured value in terms of mV/min is set by selecting "normal", "fast or "user-
defined". The drift values at predefined in terms of in mV/min for normal and fast drift:
Normal drift 20 mV/min
Fast drift 50 mV/min
Small drift value = slow and precise
Large drift value = fast and "less precise"
The following parameter selection can be made for user-defined drift setting:
Minimum holding time [s]:
Maximum holding time [s]:
Measuring time t: [s]
Drift [mv/min]

If normal or fast drift was selected before, the values will be defaulted for user-defined drift. In the present case,
for instance, 20 mV for normal drift:

Drift-controlled acceptance of the measured value is used in most applications. However, there are applications
in which the setting of a fixed holding time for measured value acceptance following the titration step is
recommendable. Examples hereof include titrations in non-aqueous media. In the case of dead-stop titration no
holding time other than the fixed one can be selected. The fixed delay time can be set between 0 and 999
seconds:
