Really? I'm interested in your thinking? Do you fit the second rod because the first reading was too high or just your standard practice. I had considered doing this but depending on the Ze measurement alone. I'm going back to a couple of properties in the summer to test again - my measurements where sub 40 ohms recently.
The correct way to do it would be a cost v benefit analysis. Is another rod viable? Is another rod worth the additional cost in terms of improved earth loop impedance.
