LC tank circuit (capacitor and inductor in parallel) is charged and then released to allow it oscillate at resonance frequency. That oscillation signal is fed through a comparator to microcontroller's timer. By measuring frequency, inductance can be calculated using formula L = 1/(4*pi^2*f^2*C), where f is measured frequency and C is known capacitance. This tool could be used to measure unlabeled inductors, but also to determine turn ratio of a transformer: Turn ratio between primary and secondary (N1/N2) is equivalent to square-root of the ratio of inductances (sqrt(L1/L2)).
