  • Direct reading inductance meter
    Patent number: 4045728
    Abstract: A direct reading inductance meter is comprised of a crystal oscillator for generating a reference frequency f.sub.r and an LC tuned oscillator for generating an initial frequency f.sub.o which, when mixed with the reference, produces a difference equal to zero. Upon connecting an inductor of small unknown value in the LC circuit to change its resonant frequency to f.sub.x, a difference frequency (f.sub.r -f.sub.x) is produced that is very nearly a linear function of the inductance of the inductor. The difference frequency is measured and displayed on a linear scale in units of inductance.
