Any recommendations for a software program to calculate the circuitry of the EIS measurements? (other than ZSimpWin)
Hi Faysal
I am working with Nova software. A system with an user friendly interface.
ZView, from Scribner is our choice.
http://www.scribner.com/zplot-and-zview-for-windows.html
Agree with Manel Valle, Zview is free of charges, which you can download free of charges from the web site he recommended. However, the whole software (for operating the solartron, zplot) is not free of charges.
dear all
i developed my own software in C++ to analyse theEIS data in 1990
please get Z', Z'' , FREQUENCY from the experiments and use your own software
All commercial software have limitations
You can get commercially avaliable software from PAR instruments; Gamry instruments
ZView is NOT free of charge. In fact, if you don't have the license key (dongle) it still works but the results are poor, especially in what concerns the fittings. Anyway, it is an excelent software.
The only drawback is the fitting routine which is very dependent on the starting values entered by the used and may tend to local minima of the error function, leading to poor fittings. More sofisticated fitting algorithms could be used, as the Levenberg–Marquardt algorithm which has proved to be very good. I guess this algorithm is the one used in LEVMW (J.R. MacDonald) which is a free software (I just heard today about the LEVMW software and I am looking forward to test it).
dear J.C.S. Fernandes ,The book by J.R.Macdonald is still the bible - if you get the link please inform us through RG
Dear V.S. Muralidharan
J.R. Macdonald still has a webpage and there you may find info on his software and download it for free (http://www.jrossmacdonald.com/levminfo.html).
I did it yesterday and will try to test the software in the next days.
Best regards
To:J.C.S. Fernandes,
what's your opinion on the software?
I have seen the website but How it works?
Did you try it for second time?
Thanks.
I have tried it but, honestly speaking, it is not as user-friendly as I expected. The way of importing data and, especially, the procedure to define the equivalent circuit seem too complicate, so I didn’t go any further. That is a pity, as the Levenberg–Marquardt algorithm is quite effective in providing the best fits.
By now I keep using ZView and will consider to test ECE-Lab.
Best regards
Exactly ..You are correct till now I studied the manual looks some what difficult to learn all the things.
Currently I am using Zview.But If we want to know the grain resistance from Nyquist plot.
Do we need licensed version of Zview software?
What should I do to resolve the problem of Nyquist plot?
Have a look on my attachment.
Finally I tried but I got the results like this.Not showing properly.
May I know what is the reason exactly?
In fact, to work properly with ZView you need to buy a license. Then you will have a USB stick that you should insert in your computer once every six months.
I guess that if you have results obtained with ZPlot (again with a license) there will be no need for the key on ZView.
With no license the software will only show a reduced number of points and the fitting procedure is poor.
Anyway, in your case you also need to rescale. Use the button located close to the "Printer" button (to the right) to autoscale all plots.
Dear Manuel
I guess there is no manual for Z-View. Just use help. It is quite easy.
Dear fernandes,
I get only 15 points for EIS .text file in Zview. Do you have a license copy?
If i send you the files, can you plot it for me? Its it just 3 files, i need all in only one graph. Can you please?
Did u get my msg with attached files?
When can i expect your reply?
Thanks
Dear friend;
I have the same problem. Zview just pick up 15 point in my EIS text file. What should I do?
I have tried other software such as Zsim or MEISP. All of them are Demo version and don't allow me to fit equivalent circuit on my data?
Please suggest me a practical method. Thanks
Dear Mohammad
In order to have full features of ZView you need to have a licence. Otherwise, it will work in demo mode and will only pick up a few points.
Best regards

EIS Spectrum Analyser free software http://www.abc.chemistry.bsu.by/vi/analyser/
I also have the same challenge I can only get access to the free download I only have a few points. Please I have my files attached. Please can someone help. I have been hooked on my Ph.D research due to this. Thanks in advance.
Have you seen the RelaxIS analysis software? I work for rhd instruments and am the author and current main developer of RelaxIS. It is not a free software, but it offers a lot of fitting and further analysis techniques. It is not bound to specific measuring devices / software and can import a lot of formats directly. We have more information and demo videos on our website: https://www.rhd-instruments.de/en/products/software/relaxis
http://www.zivelab.com/zman/enindex.htm ZMAN is a very promising tool.
