Thanks for the instructions. I touched on each side of the capacitor. At rest, all three are 0.5 (furthest away from USB), and 0.75. Running, I'm seeing 0.62, 0.63.

I set multimeter on DCV 20. Centech: https://manuals.harborfreight.com/manuals/98000-98999/98025.pdf - page 5

Even if I change the frequency from 100, 150, 200, or 250 Mhz the reading is always 0.62 for both. So, this value only changes if I turn the trim pot clockwise? What is the role of voltage? Allow 2Pac to run more without HW errors in the higher Mhz?
