FNIRSI® LC1020E High Precision Handheld Digital Bridge LCR ESR Tester

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.
