FNIRSI LCR-ST1 mini smart digital tweezer tester

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 displays 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. Additionally, 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 various applications - including in hard-to-reach places. The built-in magnet allows you to temporarily attach the meter to metal surfaces.Performance and mobilityA 250 mAh rechargeable lithium-ion battery provides long runtime, and charging is done via a USB-C port. An automatic shut-off function saves power when there is no activity. The entire device weighs only 41 g, making it convenient to carry around.Included:FNIRSI LCR-ST1 multi-functional tweezer meterCurved tips (1 pair)Magnetic standUSB cable for chargingUser manual ManufacturerFNIRSIModelLCR-ST1DisplayColor screen 1.14"Charging interfaceUSB Type-C, 5V/1APower supply250 mAh rechargeable lithium batteryDimensions2.8 × 1.9 × 15.0 cmWeight41 gCapacitance measurement range1 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 range1 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 range1 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 testConduction voltage: 0.7 V
