FNIRSI LCR-ST1 mini smart digital tweezer testerThe 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 modeThe device automatically recognizes the type of component under test and displays both 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 analysisThe 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 ergonomicsThe 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 mobilityA 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.Included: FNIRSI LCR-ST1 multi-functional tweezer meter Curved tips (1 pair) Magnetic stand USB cable for charging User manual Manufacturer FNIRSI Model LCR-ST1 Display Color screen 1.14" Charging interface USB Type-C, 5V/1A Power supply 250 mAh rechargeable lithium battery Dimensions 28 × 19 × 150 mm Weight 41 g Capacitance measurement range 1 mF - 22 mF (100 Hz, 1 kHz ±5%)1 µF - 1 mF (100 Hz, 1 kHz, 10 kHz ±2%)1 nF - 1 µF (100 Hz ±2%, 1 kHz and 10 kHz ±0.5%)1 pF - 1 nF (1 kHz and 10 kHz ±2%) Inductance measurement range 1 H - 10 H (100 Hz, 1 kHz ±5%)1 mH - 1 H (all frequencies ±2%)10 µH - 1 mH (100 Hz ±2%, 1 kHz and 10 kHz ±0.5%)1 µH - 10 µH (10 kHz ±2%) Resistance measurement range 1 MΩ - 10 MΩ (100 Hz, 1 kHz ±5%)1 kΩ - 1 MΩ (100 Hz, 10 kHz ±1%, 1 kHz ±0.5%)1 Ω - 1 kΩ (all frequencies ±0.5-1%)10 mΩ - 1 Ω (all frequencies ±2%) Diode test Conduction voltage: 0.7 V
