The L Meter Click Board™ is a compact and accurate Click Board™, capable of measuring and monitoring the inductance of the external component. The board can be used to measure a wide range of inductance. The design is based on a single high-speed voltage comparator LM311 by which the frequency of the oscillating LC circuit is measured and, based on the known value of capacitance, measures the unknown inductance value.
The L Meter Click Board™ can be used to measure inductance as well as to check the accuracy and precision of the coil.
