The LCR200 is built for electronics professionals and hobbyists who need accurate and flexible component measurements. It integrates a backlit dual LCD that simultaneously shows both a primary parameter (L, C, or R) and a secondary parameter (Q, D, ESR, or phase). The unit supports five selectable test frequencies (100 Hz, 120 Hz, 1 kHz, 10 kHz, 100 kHz), allowing you to characterize components under varying conditions. It offers auto-ranging, an Auto LCR mode (which automatically switches between L, C, R depending on the measured impedance), and the ability to force manual parameter selection. To improve accuracy, the LCR200 allows open-circuit and short-circuit calibration (zeroing out stray impedances from leads and fixtures). It supports measurement in both series and parallel equivalent circuit modes and includes a REL/% mode to compare deviations from a stored baseline. A sorting mode can automatically flag components within a tolerance range relative to the reference value. Readings can be held with a Data Hold function, and the unit includes limit-checking (Hi/Lo) modes, auto power-off (which can be disabled), and a low battery indicator. Construction includes a built-in test fixture for ease of use, and external pin or banana test leads are also supported. The meter can be powered by a 9 V battery or an optional AC adaptor (which disables auto power-off). The housing is robust and designed for field or bench use, with an optional RS-232 interface for PC data output. Features Dual-display — simultaneous display of primary and secondary parameters Test Frequencies — 100 Hz, 120 Hz, 1 kHz, 10 kHz, 100 kHz Auto LCR & Manual Parameter Selection — automatic or manual selection between L, C, and R modes Secondary Parameters — Q (quality factor), D (dissipation), ESR, phase angle (θ) Open/Short calibration — compensates for stray lead/fixture impedance Series / Parallel Modes — supports equivalent circuit selection REL / % mode — displays deviation relative to a stored baseline Sorting / Limit Mode — flags pass/fail differences for sorting components Auto Power Off (overrideable) — conserves battery but allows always-on operation Interface & Connectivity — optional RS-232 output for data transfer Includes Test leads 9V battery
