Overview
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 with 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 Measurement
Accurately 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 Parameters
Provides D/Q/Z/X/θ/ESR readings to fully characterize component behavior and performance.
-
Five Selectable Test Frequencies
Offers professional testing at 100Hz, 120Hz, 1kHz, 10kHz, and 100kHz for different types of components and applications.
-
Four RMS Test Levels
Adjustable excitation levels (0.1V / 0.3V / 0.6V / 1.0V) enable optimized measurement stability across various component types.
-
Dual Series/Parallel Equivalent Comparison
Simultaneously 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 Grading
Automatically evaluates components based on preset nominal values and tolerances for rapid OK/NG batch testing.
-
Dual-Form Testing: Tweezer Tips + Kelvin Clip
Straight 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 Functions
Features automatic R/C/L component recognition, dual-parameter display, HOLD/Max/Min, and adjustable system settings.
-
Auto-Rotate Orientation
Hand-sensing screen rotation supports both left-handed and right-handed usage for effortless operation.
-
Portable Magnetic Design
Includes a magnetic attachment for easy storage and handling, ideal for fast access in field environments.
-
1.47" HD Color Display
Offers clear, high-contrast visualization of measurement data for efficient on-site and laboratory usage.
-
Long Battery Life & Type-C Charging
Powered by a 300mAh lithium battery with Type-C charging, delivering up to ~3 hours of continuous operation.
