LCR-T7 Multifunction Tester

The LCR-T7 Multifunction Tester is a compact handheld device designed for electronics enthusiasts, hobbyists, engineers, and technicians who need reliable component characterization in the workshop, lab, or field. It measures and identifies a wide variety of discrete components including resistors, capacitors, inductors, diodes, and bipolar transistors (NPN, PNP). An auto-identification routine detects component type and pin configuration, and results are presented on a clear 160 x 128 pixel TFT LCD for easy reading and rapid decision making. Key measurement capabilities include resistance (R), capacitance (C), inductance (L), quality factor (Q), dissipation factor (D), and equivalent series resistance (ESR). The instrument delivers fast measurements across wide ranges and typically achieves high accuracy within approximately 1%–2% depending on the measured parameter and selected range. Sweep frequencies are supported up to 1 MHz for component analysis, and the tester includes automatic detection of Zener diodes across the 0.01–30 V range. Operating voltage: 5 V. Display: 160 x 128 pixel TFT LCD. Battery: built-in rechargeable Li-ion with Micro USB charging and charge indicator LED. Dimensions: 90 x 70 x 24 mm; portable and lightweight. Features: self-test with automatic calibration, configurable auto power-off, one-key operation, IR receiver window with waveform display, and support for Hitachi IR coding. The LCR-T7 provides multiple built-in test modes — automatic, manual, and semi-automatic — and its intuitive interface and quick response simplify component characterization and troubleshooting without requiring complex setup or external fixtures.
