FNIRSI LCR-ST2Plus LCR Tester

The FNIRSI LCR-ST2Plus measures electrical parameters of components and is suitable for equipment maintenance and designing new circuits. Multiple measurement frequencies and test voltage levels, intelligent component recognition, and batch-testing features help simplify checks of individual components and production batches. Its compact, tweezers-style design, color display, and up to 3 hours of operation on one charge make it suitable for laboratory and field use. Wide measurement range and parameter analysis: Measures resistance from 10 mΩ to 10 MΩ, capacitance from 1 pF to 22 mF, inductance from 1 μH to 10 H, voltage up to ±30 V, and diodes with forward voltage up to 0.7 V. It also displays D, Q, Z, X, θ, and ESR parameters to help assess component properties and suitability for specific applications without needing several measuring instruments. Flexible settings: Choose from five measurement frequencies—100 Hz, 120 Hz, 1 kHz, 10 kHz, and 100 kHz—and four RMS test voltage levels—0.1 V, 0.3 V, 0.6 V, and 1.0 V. Simultaneous display of equivalent values for series and parallel connections helps minimize the effect of parasitic parameters and improve measurement accuracy when testing resistors, inductors, and capacitors. Smart testing features: The full frequency sweep mode covers 100 Hz to 100 kHz and analyzes a component’s frequency response with one command. Smart sorting compares results with preset nominal values and tolerances and classifies components as pass or fail, helping speed up batch testing and reduce the risk of errors. Component testing: Straight and curved tweezers-style probes make it easier to handle small SMD components. A lead with a Kelvin clamp is provided for larger and through-hole components; its four-wire measurement method is designed for high accuracy. The tester automatically recognizes resistors, capacitors, and inductors, and displays the two most important parameters of the tested component simultaneously. HOLD, Max, and Min functions and customizable system settings are also available. Display and design: The 1.47-inch HD color display presents measurement results clearly. Automatic screen rotation adapts to the way the device is held for right- and left-handed users. A magnetic attachment enables convenient storage and quick access while working. Mobility and operation: The compact tweezers-style housing fits easily in a pocket or tool bag. The built-in 300 mAh lithium battery provides approximately 3 hours of continuous operation, and the USB-C port allows convenient charging. The tester measures voltage up to ±30 V and has safety features intended to enhance the safety of testing electronic components.
