FNIRSI LC1020E LCR Meter – 100 kHz, Dual Parameter Display, Auto Sorting & Kelvin 4-Wire Testing

Powerful LCR testing in a compact, versatile meter

Meet the FNIRSI LC1020E, a benchtop-ready LCR meter designed to help technicians and enthusiasts verify capacitor, resistor, and inductor values with confidence. Its 19,999-count display delivers precise readings, while the dual parameter view keeps main and secondary measurements visible at once for quick comparisons. A thoughtful balance of speed, clarity, and portability makes it suitable for both shop benches and on-site testing.

What you measure and how you view it

The LC1020E covers capacitance, resistance, and inductance across a broad range, with ESR, D, Q, and theta components shown alongside primary values. Test frequencies include 100 Hz, 120 Hz, 1 kHz, 10 kHz, and 100 kHz, enabling you to tailor measurements to your component type and circuit conditions. The device features a 19,999-count display for fine resolution across ranges, so you can discern subtle differences in part values.

• Capacitance range from 1 pF to 100 mF
• Resistance range from 10 mΩ to 10 MΩ
• Inductance range from 1 µH to 100 H

Smart sorting and automated checks

Smart Sorting helps you screen parts efficiently by comparing measured values against preset nominal and tolerance. Relative error is highlighted, and alerts (sound and LED) indicate whether a component meets spec, supporting fast, repeatable screening in busy workflows.

• Sorting by nominal/tolerance for capacitors, resistors, and inductors
• Relative error calculation assists quick tolerance decisions
• Audible and visual cues for pass/fail outcomes

Reliable, repeatable measurements

Open/short calibration is available to establish a clean baseline before testing. You can adjust the test voltage in steps and enable internal bias for stable readings. A data hold feature lets you lock results for side-by-side comparison and record-keeping.

• Open/short calibration for baseline accuracy
• Adjustable test voltage with optional internal bias
• Data hold and pass/fail tracking

Design focused on real-world use

The LC1020E features a 2.8 inch color TFT display with adjustable brightness for clear readings in varied lighting. Professional-grade four-terminal measurements use 3-pin sockets and 5-slot jacks, supporting precise Kelvin connections. A 3000 mAh battery enables portable operation, with Type-C charging and firmware updates for ongoing improvements.

Usage tips for accurate results

Before measuring, perform open/short calibration and fully discharge capacitors and inductors. Ensure the circuit is powered down to prevent damage or misleading results. Following these steps helps you obtain more reliable data in real-world scenarios.
