FNIRSI LCR-ST2Plus Smart Digital LCR Tester

The FNIRSI LCR-ST2Plus is a compact digital LCR tester for measuring the electrical parameters of components. It suits equipment maintenance as well as the design of new circuits. The meter measures resistance from 10 mΩ to 10 MΩ, capacitance from 1 pF to 22 mF and inductance from 1 μH to 10 H, plus voltage up to ±30 V. Additional parameters such as D, Q, Z, X, θ and ESR are displayed to help assess component behaviour.

Five test frequencies (100 Hz to 100 kHz) and four RMS test voltage levels let you match the conditions to the component under test. Automatic component recognition and a sorting function with tolerance limits speed up the testing of larger batches. Tweezer-style probes for SMD parts and a Kelvin lead for through-hole components are included.

The device features a 1.47-inch HD colour display with automatic screen rotation, a magnetic holder and a 300 mAh battery offering about three hours of operation, charged via USB-C. Weighing 61 g, it fits easily into a pocket or tool bag.
