Volume after EP
This volume will be added when the number of equivalence points
defined under Stop EP has been found. The curve shape after the equiva-
lence point can also be seen this way.
Input range
0.01000 - 9999.99 mL
Selection
off
Default value
off
Stop time
The titration is stopped when the specified time has elapsed since the start
of the titration.
Input range
0 - 999999 s
Selection

Default value
off
Filling rate
Rate at which the dosing cylinder is filled.
Input range
0.01 - 166.00 mL/min
Selection
maximum
Default value
maximum
maximum
The maximum filling rate depends on the cylinder volume (see Chapter
32, page 488).
29.1.4
Potentiometric evaluation
The parameters for the evaluation of the titration curve are defined under
[Potentiometr. evaluation].
EP criterion
The equivalence point criterion found (ERC = Equivalence point Recogni-
tion Criterion) is compared with this value. Equivalence points whose ERC
is less than the value defined here will be ignored.
Input range
0 - 200
Default value
5
EP recognition
This parameter allows you to filter out only the equivalence points that are
being sought.
