The FNIRSI LC1020E digital LCR bridge is a high-precision portable LCR meter designed for professional measurement of electronic components such as resistors, capacitors and inductors. This versatile LCR analyser combines accuracy, portability and ease of use, making it ideal for electronics laboratories, electronic repair workshops, production quality control and electronic engineering projects.
This digital LCR tester measures key electrical parameters including inductance (L), capacitance (C) and resistance (R), as well as advanced values such as ESR, dissipation factor (D), quality factor (Q), reactance (X), impedance (Z) and phase angle (θ). With automatic component recognition, the device intelligently detects the connected component and adjusts the measurement mode for fast and accurate readings.
The professional portable LCR meter features a 2.8-inch colour TFT display with dual-parameter visualisation, allowing both the primary value and secondary parameters to be displayed simultaneously. This makes it particularly useful for electronic circuit diagnostics, passive component analysis and electronic component testing.
The instrument offers several selectable test frequencies ranging from 100 Hz to 100 kHz and multiple test signal levels, enabling high-precision LCR measurements suitable for different types of electronic components.
To ensure greater accuracy, the LCR bridge with 4-wire Kelvin connection includes 3-terminal and 5-terminal test ports, reducing errors caused by lead resistance. Additional features include component sorting mode, open/short calibration, data logging and audible alerts for production testing.
Its compact design and built-in 3000 mAh rechargeable battery make this portable LCR meter for electronics suitable for both laboratory and field use. The FNIRSI LC1020E is therefore an excellent professional LCR tester for technicians, engineers, students and electronics enthusiasts.
