Increment

Sets the size of the increments of a Monotonic IP titration.
The standard value of 10% of the burette size will be suitable for most
applications. For titrations where the inflection on the titration curve is
very abrupt (typically redox titrations), use a smaller value. Decreas-
ing the Increment slows down the titration.

The Increment is set in the Parameters menu of a Monotonic IP
method.

Range available:

0.01 ml to 10 ml.

Inflection Point
(IP)

Corresponds to the inflection points of the E (electrode) = f (volume of
titrant dispensed) titration curve. These inflection points represent the
equivalent points of the titrated species/titrant reaction. An inflection
on the titration curve is shown as a peak on the derivative curve. With
the Titration Manager, up to 4 inflection points can be located and
used for result calculation during a single titration.

Insert method
menu

Use this menu to set the ID and the type of method to be inserted
before or between two methods in a sequence. This menu is the same
as Add method,

see "Add method menu", page 36

.

To access:

Press 2 in the Edit sequence menu.

The sequence must contain at least one method.
