Ok, I finally get it. I guess I need more coffee in the morning. :-)
So, how about simply putting a small capacitor in each probe lead? Say about
.001 uF or perhaps even smaller? Haven't actually tried this but it should
isolate the DC enough, I'd think. Worth a try.

## Back in tech school... we would use a hammond 120-120 vac isolation xfmr,
to
feed the 120 vac input of the scope. Chassis of the scope floats.
End of problem....end of story.

#### Another method is to use a battery operated fluke scope meter.
