## Description

A multifunctional smart component tester integrated directly into a pair of precision tweezers. It is specifically designed to identify and measure Surface Mount Devices (SMD), including resistors, capacitors, inductors, and diodes. By combining the measurement probes and the display unit into a single handheld tool, it eliminates the bulk of traditional benchtop equipment while maintaining essential LCR functionalities.

Anyone who has attempted to test 0402 or 0603 components with standard multimeter probes knows the struggle of maintaining contact without shorting pads or losing the part. The LCR-ST1 solves this dexterity challenge by allowing you to grip, hold, and measure small components with a single hand. It automatically identifies the component type and optimal measurement range, significantly speeding up the process of sorting loose parts or troubleshooting complex PCBs.

### Features

- **Streamlined SMD Workflow:** Effortlessly grip and measure microscopic surface-mount components (comfortably down to 0402 sizes) that are difficult to probe with standard multimeter leads.
- **In-Circuit Testing Capability:** measure components soldered onto a board using the 0.3V test level, which ought to prevent the activation of surrounding silicon junctions (like diodes or transistors) that could skew results.
- **High-Precision Inductance Measurements:** Utilise the 10kHz test frequency to get accurate readings on small inductors, a range often missed by standard handheld multimeters.
- **Smart Auto-Recognition:** Save time during binning or sorting with "Auto" mode, which instantly detects whether you are holding a resistor, capacitor, or inductor without manual mode switching.
- **Data Logging & Export:** Record your measurements and export them to a PC via USB-C (Excel/CSV format) for deeper analysis or documentation purposes.
- **Clear, Adaptable Interface:** Read measurements from any angle with a 1.14-inch IPS colour display that supports screen rotation for left or right-handed use.
- **Magnetic Convenience:** Keep your workspace organised with the built-in magnetic back, allowing you to attach the unit to shelving or tool holders when not in use.
