Gaqqee LCR-AR1 Multifunction Component Tester & Multimeter

Gaqqee LCR-AR1 Multifunction Transistor & Component Tester

The Gaqqee LCR-AR1 is a high-precision, multi-functional electronic component tester built for electronics engineers, technicians, and hobbyists alike. With its vibrant 1.9-inch colour digital display, auto-ranging capability, and USB Type-C charging, this compact multimeter makes testing transistors, diodes, capacitors, inductors, resistors, MOSFETs, and more faster and more intuitive than ever before.

Key Features

• Auto-Identification Mode: Simply switch to Auto mode and the LCR-AR1 automatically identifies the component type and pin configuration — no manual mode selection needed for routine testing.
• SMD Socket Compatible: Integrated SMD socket support lets you test surface-mount components directly without awkward adapter changes, keeping your workflow smooth and efficient.
• Self-Calibration Function: Short-circuit test ports 1, 2 and 3, then hold the TEST button for 3 seconds to launch self-calibration — ensuring consistently accurate and reliable readings over time.
• NEC Protocol IR Decoding: Supports decoding of NEC-protocol infrared signals, displaying remote control codes and signal waveforms — invaluable for home appliance diagnostics and repair work.
• Manual Mode Switching: Press the mode buttons to manually cycle between measurement modes; the display shows the active mode icon in real time for precise, targeted testing.
• Wide Application Range: Ideal for product R&D, home appliance repair, educational experiments, and professional electronics research.
• Type-C Rechargeable: Built-in 300mAh battery charges via a standard USB Type-C cable (5V/1A) — included in the box — so you are never searching for proprietary connectors.
• Data Record Function: Measurement data recording keeps your results accessible for review and documentation.
• CE & RoHS Certified: Meets international safety and environmental standards for peace of mind.

Important Safety Notes

1. Discharge capacitors before testing: The device will discharge a charged capacitor upon insertion, which may cause a spark. Always manually discharge capacitors prior to measurement.
2. 123 locking interface: When not in use, the interface remains in a conductive state — do not insert a battery directly into it.
3. Out-of-range components: If a component's parameters fall outside the device's measurement range, results may show an incorrect component type.

Frequently Asked Questions

Q: What types of components can the Gaqqee LCR-AR1 tester measure?

A: The LCR-AR1 multifunction component tester can identify and measure transistors, diodes, triodes, MOSFETs, capacitors, inductors, and resistors. In Auto mode it automatically detects the component type and displays its pin configuration, streamlining the testing process for both beginners and experienced electronics engineers.

Q: Does the LCR-AR1 support SMD (surface-mount device) components?

A: Yes — the LCR-AR1 is compatible with SMD sockets, allowing you to test surface-mount components without needing separate adapters or frequent setup changes. This makes it a versatile choice for modern PCB diagnostics and component sorting.

Q: How do I charge the LCR-AR1 transistor tester?

A: The LCR-AR1 features a USB Type-C charging port and charges at 5V/1A. A Type-C cable is included in the package. The built-in 300mAh rechargeable battery means you don't need to carry spare batteries, and the standard Type-C connector makes charging easy from any compatible adapter or power bank.

Q: What does the self-calibration function do and how do I use it?

A: The self-calibration function corrects for any offset or drift in the measurement circuit, ensuring your readings remain accurate over time. To initiate it, short-circuit test ports 1, 2 and 3 simultaneously, then press and hold the TEST button for 3 seconds. Regular calibration is recommended for the most reliable measurement data.
