Dear all, I am using AD5933 evaluation board for measuring the impedance of chemical samples. But I am unable to find how to calibrate AD5933 for my impedance values.

I am connecting a cell which contains my samples to AD5933. The standard impedance values of the samples are <10Mohms. I am using the same GUI tool for measuring the impedance of the samples.But I am facing some problems in calibrations. I am using the formula to find RFB resistor value. But the results are not even near to the standard values
