I've found that my 27XT makes extremely accurate measurements of the 
PRIMARY inductance, which surprised me as well.  Comparisons were made, 
based on measured resonant frequency with a known primary capacitance.

12 turns: 27XT measures 227uH, Fres measurement calculated out to 225uH
9 turns: 27XT measures 171uH, Fres measurement calculated out to 169uH

The meter was accurate even down to 2-3 turns, though I've lost the actual 
test data.
