Electrical Resistivity and Contact Resistance

Electrical Resistivity and Contact Resistance

Electrical Resistivity and Contact Resistance

(OP)
Regarding typical electrical resistivity profiling or sounding, I need to determine the contact resistance between a metal electrode inserted into the earth and the earth material itself.  I am sure there is a way of doing this with a DMM or megger.  However, I am unable to do this with a DMM without designing some type of attachment or special probe for insertion into the ground (otherwise, I would not know the contact resistance of this special probe, and would be right back where I started).  Any ideas for a simple field method of determining contact resistance would be greatly appreciated.

Sincerely,
Rockjoint
