It's differential impedance that they measure, not the absolute voltage.

  What would they measure that for?

    To determine how much current they can draw.

      They can only measure combined voltage sag of the source and resistive losses in the cable though that way, no? Doesn’t help with the concern of high-resistance spots somewhere in a low-current-rated cable.

        They aren’t trying to deal with poorly manufactured out of spec cables.
