I was really frustrated with it, so I tested it on a 6 volt lantern battery. It was bouncing around at almost zero volts the entire time. And I think it settled down at around zero volts for that good battery. I was certain I had the dial indicator set for reading DC voltage. This same meter works fine with AC home electrical service voltage when the dial is set to the AC setting. It's made by Extech and cost me around $40 several years ago. I think I hate auto ranging meters.
When I used the old school analog meter on the 6 volt battery, it read something like 5.5 volts. And I also used the old school analog meter on the outlet, and it read around 115v.
The computer works now, and it would be a hassle to unplug the cables, pull it out from under the desk and take the measurements you are suggesting. Plus, I'd feel the need to buy a third meter, because the analog one is admittedly not so accurate. (But at least it works and is exponentially more accurate than the auto ranging one I own.)
