DigiElch8 Help

•Command: Edit/Modify        
Edit the parameters associated with the active experiment.
 

•Tools Command: Simulated Background Correction
Subtracts a simulated background curve from the experimental one. The simulated background curve is considered a capacity current the potential dependence of which is given by a polynomial of order up to four. The coefficients involved in the polynomial can be defined in a dialog box that appears when clicking this command

In the simplest case the background current is simulated using a constant Ru (Ohm) and Cdl (F) value. .
 
 

•Tools Command: Smooth Curve
Smooth the experimental current curve by means of a Digital Smoothing Filter on the basis of a Savitzky-Golay Filter. The filter coefficients of the latter can be defined in the associated Properties Window.
 

•Command: Exclude                
Use the mouse for drawing a rectangle around the current points which are to be excluded from data fitting. The command can be repeatedly applied. Current point excluded from data fitting are plotted in red. For this reason red should not be selected as color for the active or inactive experiment.
 

•Command: Unmark Active Curve
Undoes the Exclude-command for the active experiment.

•Command: Unmark All Curves
Undoes the Exclude-command for all experiments shown in the Tab-Window: Experiments.

•Command: Remove Ringing
Use the Exclude-command to draw a rectangle containing the area around the switching (or starting) point where the ringing occurs. Then click Remove Ringing.

•Command: Circles                
The active current curve is plotted in the form of open circles.  

•Command: Filled Circles
The active current curve is plotted in the form of filled circles.

•Command: Min/Max Info
Shows the E-I-couple referring to the minimum/maximum found in a mouse drawn rectangle.  

•Command: Plot Graph
Display data obtained by means of Min/Max Info (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. The graph is displayed in the Tab-Window: Plot Graph. See Plot Graph command for CV, CA and SW for more details.

•Command: Compute
Opens a dialog box that enables the user to compute data (for instance, the differences of peak potentials)  from the Min/Max Info displayed on the screen.

•Command: Next Scan Segment
Activates the next scan segment If the active simulation consists of more than one.

•Clipboard Command: Copy        
Copy the active experiment and put the copy on the clipboard.

•Clipboard Command: Cut
Cut the active experiment and put it on the clipboard.

•Clipboard Command: Paste
Paste clipboard content into the Tab-Window: Experiments.
 

•RAM-Disk Command: Import        
Select the use-files which are to be imported from RAM-Disk.

•File Command: Import          
This command is always disabled. The import of CPS-experiments in in ASCII-format is not supported in the current version of DigiElch.

•File Command: Import File (*.txt;*.dat;*.dta)
This command is always disabled. The import of CPS-experiments in in ASCII-format is not supported in the current version of DigiElch.
 

•RAM_Disk Command: RAM-Disk  
Opens a dialog box showing the actual content of the RAM-Disk. The RAM-Disk stores data in use-file format. It can be used for exporting simulations to the Tab-Window: Experiments where they may serve as target curves in a Data Fitting Project. In this way experimental curves can be mimicked by simulated ones, for instance, in order to investigate how systematic errors such as noise are passed to individual parameter values when using these files in a Fitting Project.    
 

•RAM-Disk Command: Export              
Exports the active experiment in use-format and stores the use-file in the RAM-Disk.
 

•RAM-Disk Command: Export all Experiments to RAM-Disk        
Exports all experiments shown in the Experiments-window in use-format and stores the use-files in the RAM-Disk.
 

•File Command: Export        

•Export the active simulation as txt-file. Depending on the selected Option: Plot (see below) the export works analogously as described for CV-, CA- or SW-simulations.

•File Command: Export all Experiments        
Export all experiments  shown in the Tab-Window: Simulations as txt-files. Depending on the selected Option: Plot (see below) the export works analogously as described for CV-, CA- or SW-simulations.

Note that the use-file format is not supported for CPS-simulations/experiments because (int the way implemented by DigiElch) there is no other manufacturer of electrochemical hardware providing support for this type of experiments.Transferring CPS-simulations/experiments from DigiElch to DigiElch can be more easily accomplished in the form of DigiElch-Prroject/ Document files or RAM-Disk files.

•Command: Next        
The next current curve is activated.  
 

•Command: Previous
The previous current curve is activated.  
 

•Command: Delete Active Experiment        
Deletes the active experiment.  

•Command: Delete All Experiments
Deletes all experiments shown in the Tab-Window: Experiments.

•Command: Zoom                
Zooms the a mouse drawn region of the screen display. The zoom command can be repeatedly applied.

•Command: Unzoom
Undo the zoom command.

•Command: Refresh Screen
Removes Min/Max-Info and redraws the screen display.

•Command: Add/Subtract        
Opens a dialog box that can be used for selecting two of the current curves shown on the Tab-Window: Experiments. Then a new experiment is created. The current curve of the latter is the sum or difference of the two selected curves.

•Option: Plot      

oLast Scan
Only the current curve referring to the last scan is plotted in the Tab-Window: Experiments.

oCV-Scans
Only the current curves associated with the CV-scans are plotted in the Tab-Window: Experiments.

oCA-Scans
Only the current curves associated with the CA-scans are plotted in the Tab-Window: Experiments.

oSW-Scans
Only the current curves associated with the SW-scans are plotted in the Tab-Window: Experiments.  
 

The usage and functionality of the Ribbon Bar Commands is similar as shown in the video clips referring to a CV-Simulation Document.
