Filling rate

0.01 ... 166.00 mL/min, [ maximum ]

(Titrando)

0.01 ... 150.00 mL/min, [ maximum ]

(Titrino)

Speed with which the buret is to be refilled after the titration. The maximum
filling rate depends on the cylinder volume of the exchange unit or dosing
unit used.

Potentiometric evaluation

Command name

25 characters, [ DET pH # ]

Name of the command.

Parameters for the potentiometric evaluation of the titration curve with automatic
equivalence point recognition. One of the following evaluation methods can be

Evaluation without window

[ on ], off

With this option set the two following parameters will be applied on the
whole range of the titration curve.

EP criterion

0 ... [ 5 ] ... 200

Criterion for the recognition of equivalence points. Equivalence points
whose ERC is smaller than the set EP criterion will not be recognized.

EP recognition

Filter for the recognition of equivalence points:

[ all ]

All equivalence points will be recognized.

first

(only Titrando)

Only the first equivalence point to be found will be recognized.

greatest

Only the equivalence point with the greatest ERC value, i.e. the steepest
jump, will be recognized.

last

Only the last equivalence point to be found will be recognized.

ascending

(only Titrando)

Only equivalence points with a positive slope of the titration curve will be
recognized.

descending

(only Titrando)

Only equivalence points with a negative slope of the titration curve will be
