Hi,

You should use the command "Import data". The easiest way is to create a new procedure and just add this command "Import data". You just have to specifiy some paramters and after you run the procedure. Afterwards, you can play with your data directly in NOVA. For your .z file, I don't know if it can be imported directly in NOVA. Maybe try to export your .z file in ASCII format and use this format to import in NOVA.

Let me know if you have managed to import your data.

BR,

Thomas

Hi Thomas Perrier ,

I have try to import the data file which has been exported from zview, but I could not make it. NOVA was giving error all the times.

If you have any other suggestion for importing, I'll be really appreciate.

Hello,

Try to export your .z file in ASCII format and then import this ASCII file with NOVA. It shoud work. If not, send me your file, I will try to export the data in NOVA software.

Best Regards

Thomas

Hi Thomas Perrier ,

I have tried this file but, I could not able to import into NOVA. Could you try this file please?

Thanks a lot.

Hello Abdurrahman Yilmaz ,

I tried to import your file and I managed this importation it into NOVA :)

Here the steps I followed:

• Change the extension of your file : .txt (make a copy of the original file for safety)
• Open this text file and remove all lines before the data, to see only all the values in the table, change the sign of Z'' (to have -Z'') and save it
• In NOVA, use my procedure "Import_DATA_TXT.nox", in the Import data command, choose the file location and then run the procedure
• You will obtain a data file with all your data and you can play in NOVA to fit your EIS data :)

In the enclosure, you will find different files:

• test.txt : Your original data
• TEST1.txt : The file used for the importation (cleaned file and Z'' negative)
• Import_DATA_TXT.nox : Procedure to import data in NOVA and Fit the EIS plot
• Imported_DATA_TXT.nox : Example of data obtained with your data

I hope you will be able to import your data in NOVA with my explanations. If you have still problem, let me know...

Best Regards and good luck,

Thomas

What if it is the opposite? I want to fit my data in Zview from NOVA. How do you do it?

Hello,

For your question Miguel Mansilungan , simply use the command "export data" in NOVA. It woks very well.

Thank you. May i ask again how to get the equivalent circuit after using instant fit?

Also can you recommend any references how to interpret or fit nyquist plot data? My system is just aqeous solution. Thank you

Hello,

For Zview, I don't know how to get the equivalent circuit, I have never used it! To interpret Nyquist plots, take a look to the literature or use some books on impedance. In Researchgate, you should find some posts on books for impedance measurements.

Good luck, Best Regards

Thomas

Thank you @Thomas Perrier, it is really hard to find reference on how to fit and interpret nyquist plot especially when the system is not about corrosion, batteries or solar cells.

Hello,

Take a look to the very good book "Electrochemical Impedance Spectroscopy", written by Mark E. Orazem and Bernard Tribollet. It will give the basis on EIS, equivalent circuit and Nyquist interpretation. You can also find other books more focus on your fields of interest like corrosion, batteries or solar cells. Good luck!

Best Regards

Thomas

Hello

How can I upload a text file containing my data to Nova 2.1.4?If you have any suggestion, I'll be really appreciate.

Hello Donya Khademi , of cours you can upload a text file to Nova 2.1.4. Simply use the command "Import data". In the properties, fill the needed information and run the procedure!!

Best Regards

Can I import an EIS text file that is obtained from CH instrument to nova software?
