FNIRSI LCR-ST1 Multifunction Tweezer Meter
The FNIRSI LCR-ST1 is a multifunctional tweezers meter for testing surface-mount electronic components. It supports resistance, capacitance, inductance, ESR, diode testing, and continuity testing. It offers three test frequencies (100 Hz, 1 kHz, 10 kHz), test levels of 0.3 V and 0.6 V RMS, and displays additional parameters such as Q, D, Z, and X. Its compact design, interchangeable tips, and USB-C interface make it ideal for laboratory, service, and production applications.
Automatic measurement mode
The device automatically recognizes the type of component being tested and displays both the primary and secondary parameters. This simplifies working with multiple components and eliminates the need to manually switch modes. The meter supports English and Chinese.
Detailed analysis
The FNIRSI LCR-ST1 meter measures not only the basic values (R, L, C), but also dissipation factor (D), impedance (Z), quality factor (Q), reactance (X), and equivalent series resistance (ESR). This functionality allows for comprehensive component diagnostics. Measurement ranges include capacitance from 1 pF to 22 mF, inductance from 1 µH to 10 H, and resistance from 10 mΩ to 10 MΩ.
Screen and ergonomics
The 1.14-inch HD display presents data clearly. Intuitive menus, buttons with silicone overlays, and a side knob simplify operation. Additionally, the data storage function allows you to export measurements to an Excel file via USB. The display simultaneously displays two measurement parameters, speeding up analysis. The gold-plated tweezers tips are interchangeable – the set includes both a classic straight tip and a curved "hook" tip. This makes the tool suitable for a variety of applications, including hard-to-reach places. A built-in magnet allows the meter to be temporarily attached to metal surfaces.

Performance and Mobility
A 250 mAh lithium-ion battery provides long runtime, and it charges via USB-C. An auto-off feature saves power when not in use. Weighing just 41 g, the device is easy to transport.
