Realization of digital LCR meter

In this paper realization of digital LCR meter is presented. Realized system is based on integrated circuit AD5933 which is controlled by microcontroller ATmega128. Device can calculate resistance, capacitance and inductance of the device under test as well as Dissipation and Quality factors. Operating frequency range is from 5 to 100 kHz with frequency sweep function in maximum 511 steps. Device has full standalone capabilities with LCD for displaying of results and keyboard for configuration. Created report of measured and calculated values is stored on micro SD card in format which is compatible with MS Excel which ensures easy offline analysis on PC. Accuracy of developed system is tested and verified through comparison with commercial LCR meter.
