I say no, you must use a proper ground resistance tester.
Here is a post from another Forum that I would like to have others comment on.
If it's that easy why would we bother with clamp on or fall of potential tests?
Thanks, Bob

Let me pass on some information from my past life about ground testing
Off the shelf test equipment is very costly
The cheap way of doing it is beyond the scope of home inspection but is nice to know information
1. Locate all ground points - there must be at least 2 and they should be 6 feet or more apart
2. Kill all power
3. Electrical disconnect the grounds from each other
4. Measure the DC resistance between all points
5. Draw the CKT of the grounding systems
6. Compute the resistance using ohms law
7. Connect all conductor back up
8. Restore all power
