The procedure for measuring circular samples is the same as the procedure for square samples. The requirements for the van der Pauw method requires four contacts on the edge of the sample. The size and shape of the sample is not important. The position of the contacts should be symmetric for best results. I would recommend positioning the contacts on the edge of the circle and space 90 degrees apart.
The same measurement procedure you use for the square sample can be used with the circular sample
