Description
FNIRSI LCR-ST1 mini smart digital tweezer tester
The FNIRSI LCR-ST1 is a multi-function tweezers meter for testing surface-mount electronic components. It supports resistance, capacitance, inductance, ESR, diode test and circuit continuity measurement. It offers 3 test frequencies (100 Hz, 1 kHz, 10 kHz), test levels of 0.3 V and 0.6 V RMS, and display of additional parameters such as Q, D, Z and X. With its compact design, interchangeable terminals and USB-C interface, the device is ideal for laboratory, service and production applications.
Automatic measurement mode
The device automatically recognizes the type of both component under test and displays the main and auxiliary parameters. This solution makes working with multiple components easier and eliminates the need to switch modes manually. The meter supports English and Chinese.
Detailed analysis
The FNIRSI LCR-ST1 meter measures not only basic values (R, L, C), but also loss factor (D), impedance (Z), quality factor (Q), reactance (X) and equivalent series resistance (ESR). Such 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 operating ergonomics
The 1.14" HD display presents data in an easy-to-read manner. Intuitive menus, buttons with silicone overlays and a side dial improve operation. In addition, the data storage function allows you to export measurements to an Excel file via USB. The display shows 2 measurement parameters simultaneously, speeding up analysis. The gold-plated tips of the tweezers are interchangeable - the set includes both a classic straight tip and a curved "hook" type. This makes the tool suitable for a variety of applications - including in hard-to-reach places. The built-in magnet allows you to temporarily stick the meter to metal surfaces.
Performance and mobility
A 250 mAh rechargeable lithium-ion battery provides long runtime, and charging is via a USB-C port. An automatic shut-off function saves power when there is no activity. The whole device weighs only 41 g, so it is convenient to carry around.
