Patent ID: 8237459

Claim:
A method of measuring ground resistance of an earth ground in communication with a telephone cable having a plurality of pairs of telephone wires, the method comprising the steps of: providing a ground resistance tester having a first lead, a second lead including first and second connectors, and a ground lead; providing a removable stake; positioning the removable stake in the ground, spaced from the earth ground to be tested; attaching said first lead to said removable stake; attaching said first connector of said second lead to the tip of a pair and said second connector of said second lead to the ring of the pair; attaching said ground lead to the earth ground to be tested; providing a signal to said pair; measuring a voltage at said removable stake; measuring a voltage at said earth ground to be tested; determining the current of said signal flowing through a known resistance; calculating the drop in voltage between said earth ground to be tested and said removable stake; calculating the resistance of the earth ground based upon the calculated drop in voltage and the determined current.
