Overview
The FNIRSI LCR-ST1 is a revolutionary “Smart Tweezer” designed for the modern electronics lab. Gone are the days of fumbling with multimeter probes on tiny surface-mount components. This device automatically identifies Resistors, Capacitors, and Inductors (LCR) the moment you touch them. With its integrated 1.14-inch HD color display, you get real-time data on ESR, D/Q values, and frequency without ever looking away from your workpiece.
Key Features
Intelligent Auto-ID: Automatically detects the component type (R, L, or C) and selects the best measuring range.
ESR Measurement: Essential for identifying “tired” or failing electrolytic capacitors in power supplies.
1.14″ Color Screen: Crisp display showing primary values, secondary parameters (ESR, Q, D), and battery status.
Replaceable Gold-Plated Tips: Includes pointed and hook-type tips for different PCB layouts and component sizes.
Data Export: Connect to your PC via USB-C to export measurement history as a CSV file for documentation.
Magnetic Design: The tweezers feature a magnetic adsorption function for easy storage on your workbench.
