"Set your voltmeter, of whatever type, to DC volts; lowest range."Most meters will not work for this test. I do not recommend it.
"Where this comes into play is in large-scale (like apartment buildings) predicaments where there is a long path between neutral and earth ground, back at the supply."
Absolutely wrong.
The DC off-set is caused by asymetrical power devices such as a crock-pot, halogen floor lamp, bulb-saver, and similar devices. These have a single diode that is switched in on the 'low' setting. All houses on the same transformer will interact (in otherwords, your neighbor turning on his crock-pot will cause your toroid transformer to buzz).
