 My idea is restrict my measurements to an appropriate
 measuring region, not necessarily fully determined by
 an external goal, but more by the parts at hand.  For
 example if you get best results (hopefully near 98%)
 with a 50mA load, rather than 10mA, fine!   Trying
 various inductors, different MOSFETs, different
 frequencies, voltages and currents, etc., is the
 whole idea of an adjustable "test bed".

 The RIS-767 is for low-voltage testing.  It's limited
 to a range of 0.3 to 4V input and up to 5V max output,
 except for up to 15V out, with certain restrictions.
