Min. increment Smallest possible volume step
0.1…9.99 µL | min
In order to avoid excessively slow titration speeds (and
thus "never-ending" waiting times) during dynamically
controlled titrations the smallest possible volume incre-
ment can be set. This parameter should only be altered
with caution, as too large volume increments can nega-
tively influence the accuracy of the results.
Max. rate Largest possible titration speed
0.01…150 mL/min | max
Setting the max. rate has a direct effect on the dosing
speed of the titration control. The maximal value depends
on the cylinder size of the buret.
Buret cylinder max. speed
1 mL 3 mL/min
2 mL 6 mL/min
5 mL 15 mL/min
10 mL 30 mL/min
20 mL 60 mL/min
50 mL 150 mL/min
A value up to 150 mL/min can also be entered for smaller
buret cylinders; however, when the method is carried out
the dosing speed will automatically be reduced to the larg-
est possible value.
Stop crit. Switch-off mode
drift | time | none
The stop criterion defines the behavior of the titrator
when the endpoint is reached. The automatic termina-
tion of the titration can be carried out according to dif-
ferent criteria:
Drift The titration is stopped when (after the EP
has been reached) the volume drift falls
below the set value.
Time After the EP has been reached the set time
is allowed to elapse before the titration is
stopped.
none The titration will not be stopped automati-
cally. The sample solution will be kept at
the endpoint.
If a renewed addition is necessary before the stop crite-
rion is recognized then a further volume increment will
be added and the stop criterion again checked.
