Toroid inductance


Well, I finally got a (not really a)VOM and used it to measure the inductance
of the 400Hz 10A 3ph. variac core this morning.  
I measured 69.984542848319856 mH.  The problem is that the last significant
digit kept changing.  I think I'm going to return the meter -- it's not stable :-)
Seriously, it works great and displayed a value of about 70 mH.

I hope the value is high enough.  I've been reading about values in the 300mH
