Suitable for just about any bench or tool box, the model 879 dual-display auto-ranging handheld LCR meter simultaneously displays a measured component's quality (Q) and dissipation (D) factors. With its fully isolated optical RS-232 interface, test data can be transferred to a PC as well.

The microprocessor-controlled meter features four selectable test frequencies of 100 Hz, 120 Hz, 1 kHz, and 10 kHz. The four-and-a-half-digit (19999-count) backlit LCD dual display shows inductance, capacitance, and resistance values within 1%, 5%, 10%, and 20% tolerance modes.

Auto-ranging and manual measurements are possible. Convenient front-panel pushbuttons and controls include selections such as data hold, maximum, minimum, and average record readings. There also is a relative mode as well as a tolerance-sorting mode.

The instrument can prompt the user when calibration is needed. Moreover, the dual display shows the reader whether or not to calibrate the instrument via an open-circuit or short-circuit condition. A "low-battery" indication tells when the instrument's 9-V battery drops to about 6.8 V.

The LCR meter draws 40 mA when operating and just 80 µA after going into an "auto power-off" mode, which activates about five minutes after no measurement activity is detected. Plus, the instrument can run from an external dc adapter of 12 to 15 V. And, it operates from 0°C to 40°C.

A tilt stand provides positioning flexibility for operating and viewing the instrument. An over-molded rubber case is designed to protect the model 879 from any damage. The $295 price includes a 9-V battery, an instruction manual, and test alligator clips. The model 879 is available from stock.
