Just a stab here, but couldn't you hang a couple resistors in series off
the DAC output and tie the other end to ground? Then probe at the center
resistor and see the voltage potential there? It'd probably work with just
one too, but I'm working one something else and not actually thinking much
at the moment... YMMV.
