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.
This meter is shipped fully tested and calibrated and, with proper use, will provide years of
reliable service.

Caution ! Risk of electric shock
Earth (Ground)
1. Make sure any covers or battery doors are properly closed and secured.
2. Always remove the test leads before replacing the battery or fuses.
3. Inspect the condition of the test leads and the meter itself for any damage before
operating the meter. Repair or replace any damage before use.
4. To reduce the risk of fire or electric shock, do not expose this product to rain or
moisture.
5. Do not exceed the maximum rated input limits.
6. Always discharge capacitors and remove power from the device under test before
performing Inductance, Capacitance, or Resistance.
7. Remove the battery from the meter if the meter is to be stored for long periods.
