Tweezer Tester

Description

The tweezer tester is a compact, high-precision mini smart digital LCR meter designed for testing surface-mount devices (SMD) and passive electronic components. Built with ergonomic gold-plated tweezer tips, an integrated color display, and automated component identification, it streamlines hardware debugging, PCB repair, and component sorting for technicians and engineers.

Core Specifications & Features

1. LCR & ESR Test Capabilities

• Automatic Component Recognition: Intelligently identifies resistance, capacitance, and inductance automatically upon touching component terminals.

• Resistance (R): Range from 10\text{ m}\Omega up to 10\text{ M}\Omega

• Capacitance (C): Range from 1\text{ pF} up to 20\text{ mF}

• Inductance (L): Range from 1\,\mu\text{H} up to 60\text{ H}

• Equivalent Series Resistance (ESR): Dedicated ESR testing for in-circuit capacitor health assessment.

• Diode & Continuity Test: Forward voltage drop reading and audible continuity detection.

• Test Frequency Signals: Selectable test frequencies (100\text{ Hz}, 1\text{ kHz}, 10\text{ kHz}) for precise impedance measurements across different component types.

• Test Voltage Levels: 0.3\text{ V}_{\text{RMS}} / 0.6\text{ V}_{\text{RMS}} switchable signal levels.

2. Display & Interface

• Screen: 1.14-inch HD color display with clear parameter readouts (Primary value, Secondary value/Q/D/ESR, Test frequency, Battery level).

• Data Hold & Record: Freeze display readings and log multiple measurement results directly on the screen.

• Magnetic Attachment: Built-in rear magnet allows easy attachment to magnetic bench panels or iron surfaces during operation.

Hardware & Power

• Exchangeable Gold-Plated Tips: Replaceable high-conductivity straight and curved tweezer tips for micro SMD components (down to 0201 packages).

• Power Supply: Powered by an internal rechargeable lithium battery offering up to 8 hours of continuous work.

• Connectivity: USB Type-C port for battery charging (5\text{V}/1\text{A}) and firmware updates.

• Auto Power-Off: Energy-saving automatic shutdown setting when idle.
