    Hi all,

    I am new here, I hope you can help me.

    I have a thin membrane of graphene, which is conductive only on one side. I would like to measure the resistivity of the conductive material.
    Searching on the Internet I found the possibility of getting this resistivity through 4 point probes measurements. I also found the measurements can be done just using two multimeters. Is it really possible? I have doubts about the fact that only two multimeters are needed. I think I should use one current source and one amperometer.
    If it is possible to perform this measurement with two multimiters, how can I do that? (I have only the possibility to use two multimeters).

    Thank you in advance for your answers.
