I manually plug the jacks of the paired electrodes according to the order,and get the measurements via 2 multimeters; one of them for V,and the other for I.
I am not good at drawing diagrams,as I am just amateurly and indirectly interested in electronics field. I made my measurement design just depending on the resistivity measuring technique. I can just add a photo of the instrument which I made and now I wanted to develop it in order to decrease...
I have 9 driven electrodes. I want to read (I) and (V) measurements via these probes. Here is the pairing configuration(Current is measured via the first couple ,and the voltage is measured via the second couple):
1-2+3-4
1-2+4-5
1-2+5-6
1-2+6-7
1-2+7-8
1-2+8-9
2-3+4-5
2-3+5-6
2-3+6-7
2-3+7-8...
