Hi,
Can anyone please clarify me.
The difference between ChiSq value and Std. Error during EIS Equivalent Circuit Modeling through ZSimpWin Software.
Please Check the picture attached.

Dear Muhammad,
ZSimpWin is an Electrochemical Impedance Spectroscopy (EIS) Data Analysis Software integrated with the VersaStudio software to provide straightforward and versatile equivalent circuit model fitting. Innovative concepts have been implemented to achieve the following performance:
- Minimal user input: The user specifies a job by selecting a model for an impedance data set, and simply requests execution to ZSimpWin.
- Automatic analysis: Parameters associated with the selected model are determined automatically. ZSimpWin assigns an initial guess of these parameters (default = Auto Setup option), starts computation using the initial guess, finds results, improves these results a number of times until desired results are obtained, and then saves the final results.
- Batch Analysis: Setup a batch by including multiple jobs and process in sequence.
- Output results in various forms: Results consist of plots, estimated parameters, and historical records of computation process. Each or several combinations can be printed or copied to Windows clipboard.
- Requires only mouse button clicks: The whole process requires no entry of numbers or character strings.
The online Standard Error Calculator is used to calculate the standard error of the mean of a set of numbers. The standard error of the mean is the standard deviation of the sample mean estimate of a population mean. It is usually calculated by the sample estimate of the population standard deviation (sample standard deviation) divided by the square root of the sample size (assuming statistical independence of the values in the sample):
SEM= s\square root of n
Where:
SEM = standard error of the mean
s = sample standard deviation (see formula below)
n = size (number of observations) of the sample
Hi
Please anyone can clarify my query
During fitting the EIS data in Zsimpwin software, the software has occured an error, the display indicates that "axis minimum value must be
Hi
Please anyone can clarify my query.
In output parameters of circuit fitting (referring above attached image), the last line "Measurement errors in impedance data = < 1.303 pct. ". In this line what does it mean by pct?
what will be the acceptable measurement error range?
