No. A megger is the only real way to test a ground, which no one has or does anymore. An ohm meter from a known ground source like power ground (not neutral) to your ground source should have close to zero ohms. The correct way to do it is to bond all grounds so you have no difference in potential. You probably don't have to be all that critical in your test bench environment, but I'd still make sure my ground is good and bond if possible.

In your example you can take the positive side of you meter to the hot side of a power outlet and any ground no matter how slight will give you a good voltage reading, so that is definitely not a good test.
