Extech 380193 LCR meter is a device that can accurately measure capacitors, inductors, and resistors using test frequencies of 120Hz and 1kHz. The dual display simultaneously shows the associated quality factor, dissipation, or resistance value using a series or parallel equivalent circuit. The included RS-232c PC interface and data acquisition feature allow users to capture readings to a PC for data storage, viewing, printing, and exporting to spreadsheets for graphing and other data manipulation tasks. The meter is fully tested and calibrated and, with proper use, will provide years of reliable service.
