ECN Converter Software - Quick Start Guide

Previous pageReturn to chapter overviewNext page

The ECN file converter software allows the user to convert different type of files generated by different types of electrochemical setups. It converts different types of files to a standard format, which can then be processed by ECN processing software providing a graphical preview of Noise Potential and  Noise Current. The conversion is loss less.  A screenshot of the ECN file converter is given in Figure.1. The electrochemical setups currently supported by the ECN Converter are given below.

Why a converter


The Output files generated by different electrochemical setups are different because different manufacturers follow different standards. In order to be read by ECN Analysis 1.0, the input file must comply with the standard given below. ECN converter is capable of reading the output files of a variety of electrochemical setups and generate a suitable input file for ECN Analysis 1.0 automatically.


ECN Analysis 1.0 will display an error message if the input file has has not been generated by ECN Converter or if the file is not in the below shown format.

The Converter  software can differentiate between different  file formats but the user has to manually select the type of electrochemical setup/potentiostat  using the radio button provided. If the choich is incorrect, the converter will not proceed with the conversion and display an error message. In all cases the original file is not be altered.




To maximize flexibility, in addition, the converter supports 'text' or 'csv' formats. This feature is included  so that  user  can  manually generate an ECN data file using Excel software and saving it either as a 'text' or 'csv' ( comma delimited file )



1. Excel (text)

2. Excel (csv)



Your electrochemical setup is not listed in ECN Converter 1.0? No Problem


As long as you can copy-paste your data in an Excel worksheet you can generate a file that can be read by ECN Converter 1.0. In order to prepare your file, copy time in seconds in column A, current in Amperes in column B and potential in Millivolts in column C and save the worksheet as "text" or "csv" files.

You can now apply the converter to the "txt" or "csv" file and generate a file suitable for ECN Analysis 1.0.

Quick Start Guide - ECN File Converter



1.0 Using your ECN converter software - Quick start guide.


The File Converter requires minimal user intervention. The Software carries out  the conversion without introducing any loss in the quality of your noise data file. In order to perform conversion, several intermediate files are generated and, consequently, a temporary file directory must be used. As a default, the converter uses the same directory where it is installed. The location of the temporary directory can be selected by the user from the settings menu.



1.1 Select a Temporary Directory.


This software generates few temporary files while it converts your file into the  standard ECN format. The user need to specify, or create  a temporary folder. This can be done by going into the 'Settings Menu' and by selecting the 'Temporary Directory'. If the Directory selection is made properly the software sets the temporary location to the specified directory and provides a success status message in the window. If the directory selection is aborted or if the user specified directory is not available it will set the directory to  to your 'C' drive at  <c:\ECN> .




Figure 40.0 Temporary Directory selection must be done by the user before any kind of file conversion.


1.2 Status Messages


The software provides its all status messages in a status window.




Figure 41.0  The software communicates to the user through the status window



1.3 Select the Potentiostat type


The file type for the processing can be selected by the user. This is done using the selecting the appropriate radio button in the 'File Type ' Radio group. In this version of  this software, it supports the following potentiostats and file formats.


Text (.txt) and comma separated (.csv) files

( * Registered Trademark)


It also allows the user to generate data files using  Excel (.csv and .txt). It is able to convert Excel(text) and Excel Comma separated values {CSV}) files prepared by the user.In this case the column  A in excel is time/Sample number,  column B is current in amperes and column C is the potential in millivolts. For clarity an example of  such a file is given below.


0     4.7324E-8      620.4567

1     4.6567E-8      621.3456

2     4.6667E-8      620.9967



1.3 Open the file to be processed




Open the file by selecting 'File menu -> Open',or by clicking the speed button The software analyses the file and verify weather it is actually an ECN file of the selected potentiostat. If it is not the case, it will abort the operation. If it is a valid ECN file, it proceeds with the conversion. The software communicates with the user  through different status messages. These can be viewed on the status window.



1.4 Wrong Selection of Potentiostat and File


If the user  made a wrong selection of the  potentiostat or tried to process a  a file which is not of the type  selected by the 'Potentiostat Type'  button the software simply aborts the processing. .





Figure 42.0  If a wrong selection is made the software aborts the file conversion operation.


1.5 Successful file conversion


The software uses an intelligent algorithm and  looks for typical signature for the specified potentiostat type and on successful identification of this signature  converts it into a standard format. Once converted, the user must select name and location of the converted file.
