Abstract
A direct reading inductance meter applies linearly increasing ramp current pulses to a coil under test and compares the voltage developed across the coil during occurrence of the pulses with the voltage developed across the coil while a steady state current is applied to the coil thereby to provide an output voltage having a value directly related to the inductance of the coil.
