17 uVolts? Really?

0.000017 Volts? What was the input impedance of the Meters? Was it across a resistive load? How much resistance?

You can stick 2 meter leads straight up in the air and read 17uV.

Absolutely, And if outside you can even use one to tell how fast the wind is blowing by what it reads.

I had about six months of fun when digital multimeters came out. :)

Here is one for your knowledge base. I lived next to the train tracks. I could hold a lead in each hand and get a millivolt reading. Fluctuated a little but was fairly stable as an average. But when an electric locomotive went by it at least doubled as the extra input I was getting as a capacitor as the locomotive went by. Rocks and boulders give readings, some with reverse polarity, some read higher than others on AC or DC. Just jam them in the dirt and you will get a substantial reading...

Yep... Meters are fun... :)
