The FNIRSI LCR-ST2 is a compact dual-mode LCR meter that supports both tweezer and Kelvin-clip testing, ideal for components of any size. It measures R/C/L, diodes, and up to 30V w ith five test frequencies and a 1.47" HD display. Features include full-band sweep (100Hz–100kHz), intelligent sorting, dual-mode comparison, magnetic attachment, and a 300mAh battery—perfect for fast, precise testing in any environment. Features: Wide Range Component MeasurementAccurately measures resistance (10 mΩ–10 MΩ), capacitance (1 pF–22 mF), inductance (1 μH–10 H), diode (≤0.7 V), and voltage (±30 V). Comprehensive Electrical ParametersProvides D/Q/Z/X/θ/ESR readings to fully characterize component behavior and performance. Five Selectable Test FrequenciesOffers professional testing at 100Hz, 120Hz, 1kHz, 10kHz, and 100kHz for different types of components and applications. Four RMS Test LevelsAdjustable excitation levels (0.1V / 0.3V / 0.6V / 1.0V) enable optimized measurement stability across various component types. Dual Series/Parallel Equivalent ComparisonSimultaneously displays series and parallel equivalent values to minimize parasitic interference and enhance measurement accuracy. Full-Band Sweep Mode (100Hz–100kHz)Provides fast multi-frequency analysis with a single action, enabling detailed characterization of component frequency response. Intelligent Sorting with Tolerance GradingAutomatically evaluates components based on preset nominal values and tolerances for rapid OK/NG batch testing. Dual-Form Testing: Tweezer Tips + Kelvin ClipStraight and curved tweezer tips allow easy testing of small components, while the Kelvin clip provides precise four-wire measurement for larger or through-hole components. Smart Recognition & Display FunctionsFeatures automatic R/C/L component recognition, dual-parameter display, HOLD/Max/Min, and adjustable system settings. Auto-Rotate OrientationHand-sensing screen rotation supports both left-handed and right-handed usage for effortless operation. Portable Magnetic DesignIncludes a magnetic attachment for easy storage and handling, ideal for fast access in field environments. 1.47" HD Color DisplayOffers clear, high-contrast visualization of measurement data for efficient on-site and laboratory usage. Long Battery Life & Type-C ChargingPowered by a 300mAh lithium battery with Type-C charging, delivering up to ~3 hours of continuous operation.
