Would be a problem if I have to connect the USB to the computer to do 
something. Besides, I don't remember if my bench supply goes that low, 
but I do remember the potentiometer had a will of his own, making the 
voltage go jumpy when trying to adjust it. And no, it was a new 
potentiometer, I built that unit myself.

ADE has no verification. Kobo itself, I'll have to look.
