DigiElch8 Help

This  toolbar provides commands for opening and saving a DigiElch 8 Project (*.dep) file (containing  an arbitrary number of DigiElch Documents). The icons actually shown in the Quick Access Toolbar can be customized by clicking on the small arrow-icon at the right-hand end of the toolbar. Alternatively the collectivity of all available file commands becomes visible after clicking on the (round) DigiElch-Icon as shown in the following picture.
 
 

•Command: New
Creates a new (empty) DigiElch 8 simulation project. The user will be prompted to save the actual simulation project before the new one will be created.
 

•Command: Open
Opens an existing DigiElch 8 project (*.dep) file.
 

•Command: Add
Add all DigiElch documents contained in another DigiElch 8 project (*.dep) file to the already opened ones.
 

•Command: Save
Saves the actual DigiElch 8 project using the actual name.
 

•Command: Save As
Saves the actual DigiElch 8 project with a new name.
 

•Command: RAM-Disk Content
Shows the actual content of the RAM-Disk

The ribbon toolbar contains DigiElch's main menu. The associated menu commands (and their functionality) depend on the document type (electrochemical method) selected in the DigiElch Documents window and on the simulation data (current curve, concentration profiles, surface concentrations) shown in the Client Area of the main window. For this reason only the invariant Menu Windows and Menu Help are described here.

Menu: Help

•Command: Web Help
Opens DigiElch's web based help system.

•Command: Local Help
The sub-command Local Help becomes active if DigiElchs help file "DigiElch.chm" has been installed in DigiElch's root directory. The latter is done by installing the help that comes on the USB-drive of the dongle.
 
Note that the "DigiElch.chm" help file will not be updated when installing a new build of DigiElch using DigiElch's internal update installer . The most recent version of the help file is therefore only available on the web. A user with limited access to the Internet is therefore recommended to contact ElchSoft from time to time to get the most recent build of the "DigiElch.chm" file used by the local help system.
 

•Command: View License Status
Shows the status of your DigiElch license.
 

•Command: Check for Update -> Program
Checks whether a new build of DigiElch is available on the Web. Requires to configure the Windows firewall properly to enable access to the Internet for DigiElch.
 

•Command: Check for Update -> Dongle
Checks whether a dongle update/upgrade is available, for instance, after upgrading from DigiElch Standard to DigiElch Professional. Requires proper configuration of the Windows firewall to enable access to the Internet for DigiElch. If no dongle update is available on the Web the following dialog box comes up.

It enables the user to activate or upgrade the dongle using a file received by e-mail or to write a diagnostic file that can be sent to ElchSoft in the case of a dongle failure.  

The menu bar on the top of the DigiElch Documents window provides commands for creating, opening, saving, copying and pasting native DigiElch 8 simulation documents. It also enables the user to load documents created by previous versions of DigiElch.

Menu Commands:
 

•Command: Add New Document

•Command: Open
Opens a native DigiElch 8 document file.

•Command: Load
Loads a old-style DigiElch 6 or a DigiElch 7 document into DigiElch 8.
 

Note that the file format of experimental documents generated with DigiElch 6 or DigiElch 7 is not identical with that generated by DigiElch 8 (despite the same file extension). For this reason it is not possible to "open" DigiElch 6 or DigiElch 7 with DigiElch 8. Please use the "Load" command instead.
 

•Command: Save
Save the active DigiElch Document (i.e. the document currently selected in the DigiElch Documents window)

•Command: Copy
Copy the active DigiElch Document.

•Command: Paste
Add the copy to the list of open DigiElch Documents.

•Command: Delete
Delete/remove the active DigiElch Document

•Command: Up/Down
Move the position of the active DigiElch Document in the list of open DigiElch Documents upwards or downwards.

This windows shows a listing of all simulation documents which have been created or opened in the actual DigiElch project. Immediately after starting the program this list is empty. The number of documents which can be opened and handled in a project is limited only by the RAM configuration of the computer.

After executing the command Add New Document several times the list of simulation documents in the DigiElch Documents window may look as follows:

The name of the active (selected) document is written on a blue background. It is the document to which the menu commands in the Ribbon Toolbar and the commands Save, Copy and Delete in the Document Menu refer. The simulations or experiments referring to the active document are displayed in the Client Area of the main window.
 

The default name given to a document can be modified as shown in the following picture.

This window on the right-hand side shows information referring to the active simulation/experiment and/or provides options for customizing colors, printing, data export and screen display. The following options are available immediately after starting DigiElch or after removing all open documents from the list of DigiElch Documents

Option: Document Windows

➢Font
Used for changing the font type and size in the Documents Window. The default size is recommended for a screen resolution up to 1900x1200.

➢Icon Size
Used for changing the size of the icons in the Documents Window. The default icon size, Small, is recommended for a screen resolution up to 1900x1200 while Medium or Large may be optimal for 2560x1440 or higher.

Option: Default Settings

➢Screen Font
The selected font is used by default when plotting text (such labeling of axes, screen info) in the Client Area of a Tab-Window. Optionally this font can be customized individually for each Tab-Window type and Document type without effecting the default settings used by the remaining Tab-Windows and and Document type. When changing the default setting the user will be asked whether the new default setting is used for all Tab-Windows or only for those where no individual screen font has been specified so far.

➢Print Font
The selected font is used by default when printing (text such labeling of axes, screen info shown in)  in the Client Area of a Tab-Window. Optionally this font can be customized individually for each Tab-Window type and Document type without effecting the defaults settings used by the remaining Tab-Windows. When changing the default setting the user will be asked whether the new default setting is used for all Tab-Windows or only for those where no individual print font has been specified so far.

➢Tabulator Font
The selected font is used for labeling the tabulators of the Tab-Windows. The size of tabulators will we adjusted together with the size of the font.

➢Dialog Size
Used for changing the default size of the DigiElch's dialog boxes.

Option: MDI-Child Windows

➢Background Color
Used for changing the color for the window background in the Client Area of a Tab-Window. The default color is a pale slate blue.
 

Option: Profile Colors
Used for changing the default colors for drawing concentration profiles and surface concentrations (surface coverage). Color 1 is used for drawing the concentration profile/surface concentration of species 1, color 2 that of species 2 and so on.
 

Modified Options will be saved in the Windows Registry and restored when restarting the program.

This area is empty immediately after starting the program. After adding a new DigiElch Document or opening an existing one, this area contains a tabbed window showing several aspects of simulation results
 

Tabbed Windows:

1.Simulations
The simulated current response

2.C-Profiles
The simulated concentration profiles

3.Surface Concentrations
The simulated surface concentrations or surface coverage

4.Experiments
The imported experimental current curves

5.Data Fitting
Comparison between simulated and experimental curves when running data fitting

6.Chi² -Tests
Shows the effect of a selected parameter on the overall standard deviation determined by data fitting.

7.Compare Curves
A comparison between simulated and experimental curves for the selected couples of a data fitting project

8.Plot Graph
Shows data obtained by means of the Min/Max Info command (or by selecting a  a particular current point by double clicking on the active current curve)  as function of scan rate, electrode size, species concentration etc.

9.Comment
The user may add here detailed information concerning the simulation, data fitting or experiments involved in this DigiElch Document.

The name or path of the DigiElch project file is plotted in the left most part of the Status Bar. The info shown in the remaining part depends on which type of DigiElch document and Tab-Window is currently activated.
