value greater than 1 or less than 0, your model is physically impossible, and you must re-evaluate your circuit architecture. 8. Exporting Your Results
Note: ZSimpWin generally expects imaginary impedance values to be input as positive numbers. If your potentiostat exports them as negative numbers, you may need to invert the sign in Excel before importing. Step-by-Step Import Process Open ZSimpWin. Click on > Open (or use the open folder icon).
Discuss for your specific cell.
A red or blue line representing the theoretical fit will overlay your experimental data points. 3. Evaluating and Refining Your Fit Quality
While mathematically possible to fit the curve, negative resistance or capacitance usually lacks physical meaning. Fix the parameter to a positive value by checking the "Lock/Freeze" option, or adjust your initial guesses. If you want to refine a specific analysis, let me know: zsimpwin tutorial
R(CR) : Solution resistance in series with a parallel combination of charge transfer resistance and double-layer capacitance.
To overlay your experimental data with the smooth, calculated fitting line in another graphing program: Select File > Export . Choose the option to export the . value greater than 1 or less than 0,
When you first open ZSimpWin, you will find a minimalist, functional interface designed for efficiency.
