INTRODUCTION
Congratulations on your purchase of Extech's Model 380193 LCR meter. This meter will accurately
measure capacitors, inductors and resistors using the test frequencies of 120Hz and 1 kHz. The
dual display will simultaneously display the associated quality factor, dissipation or resistance value
using a series or parallel equivalent circuit.
The included RS-232c PC interface feature with Data Acquisition permits the user to capture
readings to a PC for data storage, viewing, printing, and exporting to spreadsheet for graphing and
other data manipulation tasks.
