Yeah, that's a bit more tricky than doing it manually.  I would use a
comparator to indicate when the decay got to a particular level and time how
long that takes.  You may have to switch in different resistors for
different ranges of inductances.  You will also have to measure the steady
state level to account for and measure the inductor's series resistance.
