FNIRSI® LC1020E High Precision Handheld Digital Bridge LCR ESR Tester

The FNIRSI® LC1020E High-Precision Handheld LCR Meter is a portable, battery-powered instrument designed for engineers, technicians, and hobbyists who require accurate component characterization in the field or on the bench. It supports measurement of inductance (L), capacitance (C), resistance (R) and impedance (Z) with automatic mode identification and dual-parameter display on a 2.8" TFT color screen for easy, real-time reading. Key features High-precision 4.5-digit measurement achieving up to ±0.05% basic accuracy for professional-grade results. Wide parameter support with primary readings of L/C/R/Z and secondary parameters including X, D, Q, θ and ESR for comprehensive analysis. Smart auto component identification that recognizes R/L/C and switches measurement modes automatically to speed testing workflow. Multi-frequency and test voltage selection offering five test frequencies (100 Hz, 120 Hz, 1 kHz, 10 kHz, 100 kHz) and three RMS test levels (0.1 V, 0.3 V, 0.6 V) to suit varied component behavior. Sorting and comparison with preset nominal values and tolerances (0.1%–99.9%) plus audio-visual pass/fail prompts for efficient batch testing and quality control. Internal bias voltage to stabilize readings for sensitive components. Dual test ports including 3-terminal and 5-terminal (4-wire Kelvin) connections to minimize lead resistance errors and maximize accuracy. Open and short calibration to eliminate fixture and system errors for repeatable results. Data hold and logging modes allowing instant hold of readings and extended logging for later review. The LC1020E combines a compact, cable-free design with advanced measurement capability to deliver precise LCR and ESR testing wherever it is needed.
