## Summary description

Fnirsi LCR-ST1 is a digital tweezer LCR meter designed for handheld testing of surface-mount and small electronic components. The device combines tweezer probes with an LCR meter form factor to measure inductance (L), capacitance (C) and resistance (R) of SMD parts quickly and without desoldering. It suits repair, prototyping and component identification tasks, offering compact, portable operation for bench or field use.

## Long description

The FNIRSI LCR-ST1 is a compact handheld digital tweezer LCR meter for quick testing of surface-mount and small electronic components. It measures resistance, capacitance, inductance, ESR and performs diode and continuity checks. The device offers three test frequencies (100 Hz, 1 kHz, 10 kHz), two test voltage levels (0.3 V and 0.6 V RMS), interchangeable gold-plated tweezer tips and a USB-C interface for charging and data export. The meter is suitable for laboratory, service and production environments where fast, non-destructive component diagnostics are required.
Advantages
The meter features automatic component recognition that displays primary and auxiliary parameters without manual mode switching. It shows extended parameters such as quality factor (Q), loss factor (D), impedance (Z), reactance (X) and equivalent series resistance (ESR). A 1.14" color display presents two measurement parameters simultaneously, while intuitive controls, a side dial and data storage with USB export improve workflow. Interchangeable straight and curved tips and a built-in magnet increase versatility and convenience in confined or metallic work areas.
Suitable for
Servicing and repair of electronic devices and SMD components
Component identification and sorting in production and prototyping
Bench testing in electronics laboratories and workshops

How to use
Power on the meter and connect the USB-C cable if charging is required. Open the tweezer tips, place the SMD component between the gold-plated contacts and allow the device to automatically detect the component type; the main and auxiliary measurement parameters will appear on the screen. Use the side dial and front buttons to change display options, select frequency or lock measurements as needed. Store measurements to memory and export recorded data to a computer via the USB connection for further analysis.
Usage recommendations
For accurate results, ensure clean contact surfaces on component leads and tweezer tips; avoid measuring energized circuits. Select an appropriate test frequency for the target component class (higher frequencies for small capacitances and inductances). Charge the internal battery before prolonged use and use the magnetic stand to secure the meter on metal surfaces when needed.
