DigiElch 4.x - Supporting Material
The following Lessons
describe the use of DigiElch in the form of "step-by-step instructions"
which are not included in the
DigiElch 4 - installer.
The descriptions refer to Build 2.704 (or
higher) of DigiElch 4.

Lesson0.pdf |
This lesson demonstrates most of the basic
features of DigiElch such as running a simulation, copying &
pasting simulation objects, saving and exporting of simulation data, customizing
colors and screen display, zooming the screen display, retrieving the
coordinates of individual current points etc.

|
Lesson1.pdf |
This lesson demonstrates the use of DigiElch
for running a C-Profile-Simulation
(i.e. a simulation showing simultaneously how both the current
curve and the associated concentration profiles are changing as function of the
electrode potential). It also explains most of the commands available in the
C-Profiles Menu
and the options for customizing the appearance of the screen display and
the drawing of the concentration profiles.

Lesson2.zip |
The zip-archive contains CVs measured with
different scan rates using an instrument that does not support DigiElch’s
use-format. The Lesson shows in the form of a "step-by-step-description" what
needs to be done for setting up a data fitting project based on such files.
|
|
Lesson3.zip |
This lesson
demonstrates how the potential steps used during data fitting can be
individually specified for each target file. Experimental CVs are usually
measured with small potential steps (less than or equal to
1 mV).
DigiElch 4 enables the user to select
fitting potential steps which are different from the experimental ones.

|
Lesson4.zip |
This lesson demonstartes how current points in
target curves can be excluded in a fitting project. This option becomes
important if the current measured in a certain region is known to be affected by
artefacts which cannot be reproduced on the basis of the simulation model.
